Metabolite Identification
Common Name7-Methylxanthine
Description7-Methylxanthine, also known as 7-methylxanthine, belongs to the class of organic compounds known as xanthines. These are purine derivatives with a ketone group conjugated at carbons 2 and 6 of the purine moiety. 7-Methylxanthine exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. 7-Methylxanthine exists in all living organisms, ranging from bacteria to humans. 7-Methylxanthine participates in a number of enzymatic reactions, within cattle. In particular, 7-Methylxanthine and formaldehyde can be biosynthesized from paraxanthine; which is catalyzed by the enzyme cytochrome P450 1A2. In addition, 7-Methylxanthine can be converted into 7-methyluric acid; which is mediated by the enzyme xanthine dehydrogenase/oxidase. In cattle, 7-methylxanthineee is involved in the metabolic pathway called the caffeine metabolism pathway.
