xanthine
Purine metabolism intermediate
Xanthine is a compound found naturally in body tissues and fluids, formed during the breakdown of purines.
It's an intermediate in the metabolic pathway that produces uric acid.
Caffeine, theobromine, and theophylline are methylated xanthines—stimulants found in coffee, tea, and chocolate.
The term appears mainly in biochemistry and pharmacology: xanthine oxidase, xanthine derivatives.
