Metabolite Identification
Common NameTheobromine
DescriptionTheobrominee, also known as theobromine, 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. Theobrominee exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Theobrominee exists in all living organisms, ranging from bacteria to humans. Theobrominee participates in a number of enzymatic reactions, within cattle. In particular, Theobrominee and formaldehyde can be biosynthesized from caffeine through the action of the enzymes cytochrome P450 1A2 and cytochrome P450 2E1. In addition, Theobrominee can be converted into 3,7-dimethyluric acid through the action of the enzyme xanthine dehydrogenase/oxidase. In cattle, theobrominee is involved in the metabolic pathway called the caffeine metabolism pathway.
