Xanthine, a plant alkaloid found in tea, coffee, and cocoa, is a mild stimulant of the central nervous system. Xanthine also acts as an intermediate product on the pathway of purine degradation^[1][2][3].

A number of stimulants are derived from Xanthine including caffeine and theobromine. Xanthine is a product on the pathway of purine degradation. Xanthine is subsequently converted to uric acid by the action of the Xanthine oxidase enzyme.
