Metabolite Identification
Common NameCaffeine
DescriptionCaffeine, also known as caffeine or caffeine, 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. Caffeine is a drug which is used for management of fatigue, orthostatic hypotension, and for the short term treatment of apnea of prematurity in infants. Caffeine exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Caffeine participates in a number of enzymatic reactions, within cattle. In particular, Caffeine can be converted into paraxanthine and formaldehyde through its interaction with the enzyme cytochrome P450 1A2. In addition, Caffeine can be converted into theobromine and formaldehyde; which is mediated by the enzymes cytochrome P450 1A2 and cytochrome P450 2E1. In cattle, caffeine is involved in the metabolic pathway called the caffeine metabolism pathway. Caffeine is a potentially toxic compound.
