Application
Paraxanthine: The Main Metabolite of Caffeine
Paraxanthine is the main metabolite of caffeine [C2042]. Caffeine metabolites, such as paraxanthine, theophylline [T0179], theobromine [T0178] and other xanthine derivatives, play an important role in the biochemical processes of mammalian organisms.
