CBD and other plant cannabinoids can potentially interact with many pharmaceuticals by inhibiting the activity of cytochrome P, a family of liver enzymes. Feb 26, Potent inhibition of human cytochrome P 3A isoforms by cannabidiol: role of phenolic hydroxyl groups in the resorcinol moiety. Yamaori. Cannabinoids and Cytochrome P Interactions. involvement of the endocannabinoid system and cannabinoid ligands in the regulation of CYP liver activity.
System Cannabidiol in P-450 the Cytochrome
However, certain substances have the ability to affect processing times within this system, making drugs metabolize faster or slower than they would on their own. Similarly, if the cytochrome P system is unhealthy due to problems with the liver or other pre-existing conditions, drugs may not metabolize as they should. Grapefruit , watercress , St. When the CYP system is impacted in this way, it leads to higher levels of certain drugs in your system at one time.
This can cause unwanted side effects, and sometimes, an overdose. From there, the two of you may consider adjusting the dosage on your medications so that you can use both products safely. Any drug metabolized by CYP enzymes could potentially interact with cannabidiol.
This list does not include all of the potential medications impacted by cannabidiol. Nor will every medication in the categories contained on this list will cause an interaction. In other words, you ingest an inactive compound and once in the body, it is processed into the active drug. If this processing is dependent on CYP3A4 part of the larger CYP system , then inhibitors can result in too little active drug in the body for the desired therapeutic effect. Codeine , for example, is a prodrug that is metabolized into morphine which provides the effect.
Vyvanse and Concerta are two other popular pharmaceutical medications for ADHD that fall into this category. If you are worried that your CYP pathway may not be functioning properly, physicians can test the system to ensure that the medications you take are metabolizing as expected. Alcohol and cannabis are both widely consumed in our society and the effects of combining the two are well known.
What is less understood by the general public, is the effects of combining alcohol and the cannabinoid compound CBD. Alcohol depends on a few different metabolic pathways in the human body, with the primary enzymes involved being: Although the pharmacokinetics of alcohol and CBD are not yet well-understood, what we do know is CBD inhibits the CYP enzyme system, and this system plays a significant role in alcohol metabolism. It is important to be mindful and cautious when mixing CBD and alcohol.
As it turns out, the two substances go very well together! Caffeine is molecularly very similar to adenosine , a compound produced in our bodies that activates the A2a receptor. Caffeine binds to the A2a receptors, inhibiting the reuptake of adenosine.
Consequently, blocking adenosine from binding results in vasodilation , which increases clarity and alertness.
It is worth noting that these effects depend on the serving size of the CBD. High amounts of CBD are more likely to cause drowsiness and sedation. This can mean the effects of the caffeine will be more prolonged and drawn out.
The can be both good and bad! Considering this information, again, it is best to be mindful and cautious when mixing caffeine and CBD. One of the most common questions we get is: Can I get addicted to CBD oil? Cannabidiol is not physically addictive in the same way opiates, cocaine, alcohol, and other drugs can be.
But, having said that, human beings can get addicted to just about anything including exercise, music, sex, and food.
Information and education will be your most powerful weapons going forward. When taking cannabidiol, it is important to consume only the recommended serving size. Raising or lowering this amount may produce the opposite of the desired effect. Keep in mind that some people may metabolize cannabidiol differently because of anomalies within the cytochrome P45O CYP enzyme system.
And depending on when you take your medications, you may find an unintended increase or decrease in CBD concentrations in your blood. Also, you may refer to our page on dosing CBD oil for additional information. Your email address will not be published. What is CBD Oil? Is CBD for Pets? If your furry friend has been suffering from a What is the Clinical Endocannabinoid Deficiency Syndrome? Cannabinoids are chemical compounds that naturally occur in the resin of the Cannabis sativa plant, commonly called I take 50mg of tramadol 3xs a day for the past 8 years.
Can I use cbd oil in conjuction with them? Customer Care January 16, Hi, Since we are not licensed practitioners or doctors, so we are not legally able to answer that question. Cannabinoids like CBD may interact with prescription drugs, dietary supplements, and over-the-counter drugs.
Always check with your licensed physician or prescribing doctor before using CBD if you are concerned. Also, a holistic doctor or someone in the Chinese medicine field might be able to answer some of your questions and be more versed in the land of CBD.

Teri Moerschel December 30, To determine, via narrative, non-systematic review of pre-clinical and clinical studies, whether the effect of cannabis on hepatic biotransformation pathways would be predicted to result in clinically significant drug-drug interactions DDIs with commonly prescribed psychotropic agents.
A non-systematic literature search was conducted using the following databases: The search term cannabis was cross-referenced with the terms drug interactions, cytochrome, cannabinoids, cannabidiol, and medical marijuana. Bibliographies were also manually searched for additional citations that were relevant to the overarching aim of this paper.
In addition, there have been reports regarding THC inclination to P-gp P-glycoprotein efflux, fur- ther limiting its absorption   .
Piperine-pro-nanolipospheres as a novel oral delivery system of cannabinoids: Pharmacokinetic evaluation in healthy volunteers in comparison to buccal spray administration. However, the oral consumption of the molecules is very limited due to their highly lipophilic nature that leads to poor solubility at the aqueous environment. These absorption obstacles render the molecules with low and variable oral bioavailability. To overcome these limitations we designed and developed the advanced pro-nanolipospheres PNL formulation.
The PNL delivery system is comprised of a medium chain triglyceride, surfactants, a co-solvent and the unique addition of a natural absorption enhancer: Piperine was selected due to its distinctive inhibitory properties affecting both Phase I and Phase II metabolism. This constellation self emulsifies into nano particles that entrap the cannabinoids and the piperine in their core and thus improve their solubility while piperine and the other PNL excipients inhibit their intestinal metabolism.
Another clear advantage of the formulation is its composition of materials approved for human consumption. The safe nature of the excipients enabled their direct evaluation in humans. The trial comprised of 9 healthy volunteers under fasted conditions.
Single oral administration of the piperine-PNL formulation resulted in a 3-fold increase in Cmax and a 1. For CBD, a 4-fold increase in Cmax and a 2. These findings demonstrate the potential this formulation has in serving as a standardized oral cannabinoid formulation.
Moreover, the concept of improving oral bioavailability described here, can pave the way for other potential lipophilic active compounds requiring enhancement of their oral bioavailability. A high percentage of free-CBD is excreted in the feces [17, 18]. Impact of enzymatic and alkaline hydrolysis on CBD concentration in urine. A sensitive and specific analytical method for cannabidiol CBD in urine was needed to define urinary CBD pharmacokinetics after controlled CBD administration, and to confirm compliance with CBD medications including Sativex—a cannabis plant extract containing 1: Non-psychoactive CBD has a wide range of therapeutic applications and may also influence psychotropic smoked cannabis effects.
Solid-phase extraction isolated and concentrated analytes prior to GC-MS. Enzyme-hydrolyzed urine specimens exhibited more than a fold CBD concentration increase compared to alkaline and non-hydrolyzed specimens. This method can be applied for urinary CBD quantification and further pharmacokinetics characterization following controlled CBD administration. The involvement of CYP is only part of the metabolism of CBD  , which has been linked to many other enzymes involved in the control of redox.
Oxidation of xenobiotics can potentially produce highly reactive intermediates and is why phase I and II metabolism is integrated with electrophilic sensors [e. Molecular Targets of Cannabidiol in Neurological Disorders. Cannabis has a long history of anecdotal medicinal use and limited licensed medicinal use. Until recently, alleged clinical effects from anecdotal reports and the use of licensed cannabinoid medicines are most likely mediated by tetrahydrocannabinol by virtue of: However, there has recently been considerable interest in the therapeutic potential for the plant cannabinoid, cannabidiol CBD , in neurological disorders but the current evidence suggests that CBD does not directly interact with the endocannabinoid system except in vitro at supraphysiological concentrations.
Thus, as further evidence for CBD's beneficial effects in neurological disease emerges, there remains an urgent need to establish the molecular targets through which it exerts its therapeutic effects. Here, we conducted a systematic search of the extant literature for original articles describing the molecular pharmacology of CBD.
We critically appraised the results for the validity of the molecular targets proposed. Thereafter, we considered whether the molecular targets of CBD identified hold therapeutic potential in relevant neurological diseases.
The molecular targets identified include numerous classical ion channels, receptors, transporters, and enzymes. Some CBD effects at these targets in in vitro assays only manifest at high concentrations, which may be difficult to achieve in vivo, particularly given CBD's relatively poor bioavailability.
Moreover, several targets were asserted through experimental designs that demonstrate only correlation with a given target rather than a causal proof. When the molecular targets of CBD that were physiologically plausible were considered for their potential for exploitation in neurological therapeutics, the results were variable.
In some cases, the targets identified had little or no established link to the diseases considered.
In others, molecular targets of CBD were entirely consistent with those already actively exploited in relevant, clinically used, neurological treatments. Finally, CBD was found to act upon a number of targets that are linked to neurological therapeutics but that its actions were not consistent withmodulation of such targets that would derive a therapeutically beneficial outcome.
We conclude that CBD is very unlikely to exert effects in neurological diseases through modulation of the endocannabinoid system. Moreover, a number of other molecular targets of CBD reported in the literature are unlikely to be of relevance owing to effects only being observed at supraphysiological concentrations.
Of interest and after excluding unlikely and implausible targets, the remaining molecular targets of CBD with plausible evidence for involvement in therapeutic effects in neurological disorders e. While no causal proof yet exists for CBD's effects at these targets, they represent the most probable for such investigations and should be prioritized in further studies of CBD's therapeutic mechanism of action.
The cannabinoids are primarily metabolized by the liver cytochrome P CYP enzymes. Cannabis has been used for centuries to treat seizures. Recent anecdotal reports, accumulating animal model data, and mechanistic insights have raised interest in cannabis-based antiepileptic therapies. In this study, we review current understanding of the endocannabinoid system, characterize the pro- and anticonvulsive effects of cannabinoids [e.
These studies suggest that CBD avoids the psychoactive effects of the endocannabinoid system to provide a well-tolerated, promising therapeutic for the treatment of seizures, while whole-plant cannabis can both contribute to and reduce seizures. Finally, we discuss results from a new multicenter, open-label study using CBD in a population with treatment-resistant epilepsy.
In all, we seek to evaluate our current understanding of cannabinoids in epilepsy and guide future basic science and clinical studies.
Cannabinoids in the Treatment of Neurological Disorders vol 12, pg , Government should help to protect people from harm—whether the harm comes from spending money on products that do not deliver on their promise or have the potential to cause adverse effects that do not outweigh their beneficial effects. Another limitation of the current study is that CBD metabolites were not examined, as no analytical standards for these compounds were commercially available.
ABC transporters P-gp and Bcrp do not limit the brain uptake of the novel antipsychotic and anticonvulsant drug cannabidiol in mice. Cannabidiol CBD is currently being investigated as a novel therapeutic for the treatment of CNS disorders like schizophrenia and epilepsy. ABC transporters such as P-glycoprotein P-gp and breast cancer resistance protein Bcrp mediate pharmacoresistance in these disorders.
P-gp and Bcrp are expressed at the blood brain barrier BBB and reduce the brain uptake of substrate drugs including various antipsychotics and anticonvulsants. It is therefore important to assess whether CBD is prone to treatment resistance mediated by P-gp and Bcrp. Moreover, it has become common practice in the drug development of CNS agents to screen against ABC transporters to help isolate lead compounds with optimal pharmacokinetic properties.
CBD results were compared with the positive control risperidone and 9-hydroxy risperidone, antipsychotic drugs that are established ABC transporter substrates. These results suggest that CBD is not a substrate of P-gp or Bcrp and may be free from the complication of reduced brain uptake by these transporters.
Such findings provide favorable evidence for the therapeutic development of CBD in the treatment of various CNS disorders. This is consistent with findings from a study which used human liver microsome preparations and also reported that the main hepatic enzymes involved are CYP3A4 and CYP2C19 Jiang et al. Does cannabidiol have a role in the treatment of schizophrenia?
Schizophrenia is a debilitating psychiatric disorder which places a significant emotional and economic strain on the individual and society-at-large. Unfortunately, currently available therapeutic strategies do not provide adequate relief and some patients are treatment-resistant.
In this regard, cannabidiol CBD , a non-psychoactive constituent of Cannabis sativa, has shown significant promise as a potential antipsychotic for the treatment of schizophrenia. However, there is still considerable uncertainty about the mechanism of action of CBD as well as the brain regions which are thought to mediate its putative antipsychotic effects.
We argue that further research on CBD is required to fast-track its progress to the clinic and in doing so, we may generate novel insights into the neurobiology of schizophrenia. Any differences in the PK pro- file for HT-treated animals could be a consequence of the retardation in kinetics that occurs in cooled animal. Also, HT increases plasma lev- els of drugs with cytochrome Prelated metabolism Anderson et al. After repeated dosing on the last day of administration there was no evidence for any accumulation of CBD or its metabolites in plasma or brain when compared to a single dose.
Neuroprotection by cannabidiol and hypothermia in a piglet model of newborn hypoxic-ischemic brain damage. Hypothermia, the gold standard after a hypoxic-ischemic insult, is not beneficial in all treated newborns. Cannabidiol is neuroprotective in animal models of newborn hypoxic-ischemic encephalopathy. This study compared the relative efficacies of cannabidiol and hypothermia in newborn hypoxic-ischemic piglets and assessed whether addition of cannabidiol augments hypothermic neuroprotection.
Hemodynamic or respiratory parameters as well as brain activity aEEG amplitude were monitored throughout the experiment.
HI led to sustained depressed brain activity and increased microglial activation, which was significantly improved by cannabidiol alone or with hypothermia but not by hypothermia alone. No treatment modified the effects of HI on oxidative stress or astroglial activation. Cannabidiol treatment was well tolerated. Some studies have also proposed that CYP2C19 is important in the metabolism of the exogenous cannabinoid cannabidiol, thus suggesting that other endogenous cannabinoids could be potential substrates as well [54, 55].
However this area of research need to be extended and confirmed before any firm conclusions can be drawn. Implications for Behavior, Psychopathology and Treatment. Mood and anxiety disorders are a major burden to the society today but still the pathophysiology behind these disorders is largely unknown and the pharmacotherapy available today is far from sufficient, with relatively low remission rates. Knowledge about the CNS specific action of these enzymes might in the future provide an increased understanding of the pathogenesis and pathophysiology of these disorders.
Here we present an update of the research carried out in human and animal models with focus on the roles of CYP2C19 and CYP2D6 for brain development and function mediated by the metabolism of endogenous compounds. The low oral bioavailability is attributed to poor water solubility and extended firstpass metabolism.
Unlike THC or any other cannabinoid, another prominent metabolic route of CBD is direct glucuronidation of the parent compound, leading to the formation of an O-glucuronide Harvey and Mechoulam, The PNL is composed of lipid and emulsifying excipients of GRAS status and are known to increase solubility and reduce Phase I metabolism of lipophilic active compounds. These molecules are natural alkaloids and phenolic compounds which were reported to inhibit certain phase I and phase II metabolism processes.
Here we use piperine, curcumin and resveratrol to formulate the Advanced-PNL formulations. This co-localization provides an increase in CBD and THC bioavailability by its effect at the pre-enterocyte and the enterocyte levels of the absorption process. These novel results pave the way to utilize piperine-PNL delivery system for other poorly soluble, highly metabolized compounds that currently cannot be administered orally. CBD combination generates a different phenotype is that the metabolism of each of the cannabinoids is regulated at least, in part, by the same CYP enzymes.
We recently showed that acute THC administration drives region-dependent changes in the mouse brain lipidome. This study tested the hypothesis that cell lines representing cell types present in the central nervous system CNS , neurons N18 cells , astrocytes C6 glioma cells , and microglia BV2 cells would respond differently to THC, CBD, or their combination. CBD with a few exceptions.
However we did not find any literature to directly support this. Therefore we investigated, in Wistar rats, effects of pulmonary, oral and subcutaneous sc. While cannabinoid serum and brain levels rapidly peaked and diminished after pulmonary administration, sc. In contrast, oral CBD produced mild hyperlocomotion. In conclusion, oral administration yielded the most pronounced behavioural effects which corresponded to the highest brain levels of cannabinoids.
Of central importance was the novel finding that THC can be detected in serum and brain after administration of CBD alone which, given the increasing medical use of CBD-only products, has important legal and forensic ramifications.
Conjugated metabolites are mostly found in the urine Figure 3. The existence of an enterohepatic cycle and renal reabsorption trans- lates into prolonged psychoactive effects, which may in the case of an isolated intake for min after consumption has ceased   . Cannabis and Anti-Cancer Drugs: Cannabis is a plant that has been used for centuries to relieve a wide range of symptoms. Since the s, interest in medical research into this plant has grown steadily.
Already very popular for recreational use, a growing number of consumers not accustomed to using cannabis for psychoactive purposes, have begun to use it as an alternative or complement to mainstream pharmaceutical medicines. This article is protected by copyright. Modern Medicines Derived from Cannabis. Clinical pharmacology of medical cannabinoids in chronic pain.
Jun Rev Med Suisse. In Switzerland, medical cannabinoids can be prescribed under compassionate use after special authorization in justified indications such as refractory pain. Evidence of efficacy in pain is limited and the clinical benefit seems to be modest.
Their drug-drug interactions DDI profile is poorly documented. Cytochromes P CYP 2C9 and 3A4 are involved in the metabolism of tetrahydrocannabinol and cannabidiol, which implies possible DDI with CYP inhibitor and inducer, such as anticonvulsivants and HIV protease inhibitors, which may be prescribed in patients with neuropathic pain.
Drug-drug interaction between clobazam and cannabidiol in children with refractory epilepsy. Under an expanded access investigational new drug IND trial, cannabidiol CBD is being studied as a possible adjuvant treatment of refractory epilepsy in children. Of the 25 subjects in the trial, 13 were being treated with clobazam CLB. Demographic information was collected for each subject including age, sex, and etiology of seizures, as well as concomitant antiepileptic drugs AEDs. Side effects were monitored.
Medical Marijuana in the Workplace: Challenges and Management Options for Occupational Physicians. Although possession and use of marijuana is prohibited by federal law, legalization in four states Alaska, Colorado, Oregon, and Washington and allowance for palliation and therapy in 19 others may reposition the drug away from the fringes of society.
This evolving legal environment, and growing scientific evidence of its effectiveness for select health conditions, requires assessment of the safety and appropriateness of marijuana within the American workforce.
Although studies have suggested that marijuana may be used with reasonable safety in some controlled environments, there are potential consequences to its use that necessitate employer scrutiny and concern. Marijuana in the Workplace: Guidance for Occupational Health Professionals and Employers: Employers are often put in a difficult position trying to accommodate state laws that allow the use of marijuana for medical purposes while enforcing federal rules or company drug-use policies based on federal law.
Although it appears that in most states that allow medical marijuana use, employers can continue enforcing policies banning or restricting the use of marijuana, this approach may change on the basis of future court decisions. The Joint Task Force recommends that marijuana use be closely monitored for all employees in safety-sensitive positions, whether or not covered by federal drug-testing regulations.
Best practice would support employers prohibiting marijuana use at work. Employers, in compliance with applicable state laws, may choose to simply prohibit their employees from working while using or impaired by marijuana. In some states, employers may choose to prohibit marijuana use by all members of their workforce whether on or off duty.
Nevertheless, in all cases, a clear policy to guide decisions on when marijuana use is allowed and how to evaluate for impairment must be widely distributed and carefully explained to all workers. Legal consultation during policy development and continual review is imperative to ensure compliance with federal, state, and case law.
Drug-use and drug-testing policies should clearly delineate expectations regarding on-the-job impairment and marijuana use outside of work hours. Specific criteria for use by supervisors and HR personnel when referring employees suspected of impairment for an evaluation by a qualified occupational health professional are critical.
Detailed actions based on the medical evaluation results must also be clearly delineated for HRs, supervisors, and workers. The Joint Task Force recommends that employers review the following points when developing workplace policies that address marijuana use in the workplace: For employees covered by federal drug testing regulations eg, DOT and other workers under federal contract , marijuana use, both on or off the job, is prohibited.
Thus, employers may use urine drug screening in this population. Employees in safety-sensitive positions must not be impaired at work by any substance, whether it be illicit, legally prescribed, or available over-the-counter. Employers may consider prohibiting on the job marijuana use for all employees in safety-sensitive positions, even when not covered by federal drug testing regulations.
When employers allow medical marijuana use by employees, consultation with a qualified occupational health professional is recommended. Employers residing in or near states that allow the use of recreational marijuana must establish a policy regarding off-work use of marijuana. In many states, the employer may choose to prohibit employees from simply working while using or under the influence of marijuana or may choose to prohibit marijuana use both on and off the job.
Urine drug testing above traditional cutoff levels, or serum testing at any level, would be reasonable criteria for the employer wishing to ban both on- and off-the-job use.
Legal consultation is strongly recommended. Although it appears that in most states that allow the use of medical marijuana, employers may be able to continue policies banning or restricting the use of marijuana as previously discussed, this practice may change on the basis of future case law. Currently the ADA does not apply in these situations because marijuana is illegal under federal law. Legal consultation is again strongly recommended. Two samples should usually be obtained as a second confirmatory test may be needed.
An MRO is most helpful in helping determine these types of cases because legal testimony may be required. All employers should have clear policies and procedures for supervisors to follow regarding the criteria for identifying potential impairment and the process for referring an employee suspected of impairment for an occupational medical evaluation. Policies should include action required by HR personnel based on the results of the examination. Employee education is vital to ensure compliance with company expectations.
Education is needed at hire and again at regular intervals. At a minimum, employees should learn how chemical substances affect their health, safety, personal behavior, and job performance. Supervisors and employees should also be educated about how to recognize behaviors indicative of impairment, whether the source is medical marijuana, prescription medications, illegal drugs, alcohol, over-the-counter medications, fatigue, or any combination thereof.
In states where marijuana use is permitted, employers should provide educational resources regarding the detrimental effects of marijuana use, including caution regarding dose and delayed effects of edible products. The safety of workers and the public must be central to all workplace policies and employers must clearly articulate that legalization of marijuana for recreational or medical use does not negate workplace policies for safe job performance.
The evolving legal situation on medical and recreational marijuana requires employers to consult with legal experts to craft company policy and clarify implications of impaired on-duty workers. This changing environment surrounding marijuana use requires close collaboration between employers, occupational health professionals, and legal experts to ensure that workplace safety is not compromised. Polymorphic expression of CYP2C19 and CYP2D6 in the developing and adult human brain causing variability in cognition, risk for depression and suicide: In this paper, the in vitro microsomal hepatic metabolism of the antiasthmatic prototype LASSBio and the structural identification of its major phase I metabolites were described.
Incubation with pooled rat liver microsomes converted LASSBio to the following major metabolites: These metabolites were formed by the dealkylation step of 3,4-dimethoxyphenyl and 1,3-benzodioxole subunits, respectively, in agreement with the in silico prediction using MetaSite Program. Cannabinoids in the Treatment of Neurological Disorders. The force of the recent explosion of largely unproven and unregulated cannabis-based preparations on medical therapeutics may have its greatest impact in the field of neurology.
Paradoxically, for 10 millennia this plant has been an integral part of human cultivation, where it was used for its fibers long before its pharmacological properties. The effects of three or four different inhibitor concentrations on the formation of resorufin were examined at five substrate concentrations to characterize the enzyme kinetics for the inhibition of human CYP1A1 by CBD and its related compounds.
Lineweaver—Burk plots of enzyme kinetic data were generated to determine the mode of inhibition. Chirality , 17, 37—43 Each point is the mean of duplicate determinations.
To determine whether free phenolic hydroxyl group s in the pentylresorcinol moiety of CBD has a role in CYP1A1 inhibition, the inhibitory effects of two methylated derivatives of CBD were investigated.
CBD and olivetol contain a pentyl side chain in their structures. CBDV possessing a shorter side chain i. B Recombinant human CYP1A1 was incubated with 7-ethoxyresorufin in the presence of various amounts of orcinol and resorcinol. As shown in Fig. Hydrogen bonds are shown as dashed lines. Identification of cytochrome P enzymes responsible for metabolism of cannabidiol by human liver microsomes.
Differential inhibition and inactivation of human CYP1 enzymes by trans -resveratrol: The structure of the resorcinol moiety in CBD contains two free phenolic hydroxyl groups and a phenyl ring, which are likely to interact with amino acids within the active site of CYP1A1. Furthermore, our molecular modeling supports the importance of two free phenolic hydroxyl groups in CYP1A1 inhibition.
This result reveals that the mechanism underlying CBD-mediated CYP1A1 inhibition cannot be explained only by the presence of two free phenolic hydroxyl groups of the phytocannabinoid. The importance of the Phe residue in ligand binding has been shown by previous studies. Comparative homology modeling of human cytochrome PA1 CYP1A1 and confirmation of residues involved in 7-ethoxyresorufin O -deethylation by site-directed mutagenesis and enzyme kinetic analysis.
