Metabolite Identification
Common Name1-Methylxanthine
Description1-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. 1-Methylxanthine is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 1-Methylxanthine exists in all living organisms, ranging from bacteria to humans. 1-Methylxanthine participates in a number of enzymatic reactions, within cattle. In particular, 1-Methylxanthine and formaldehyde can be biosynthesized from theophylline; which is mediated by the enzyme cytochrome P450 1A2. In addition, 1-Methylxanthine can be converted into 1-methyluric acid through its interaction with the enzyme xanthine dehydrogenase/oxidase. In cattle, 1-methylxanthine is involved in the metabolic pathway called the caffeine metabolism pathway.
