Coffee and Chocolate Chemistry


Caffeine. 1,3,7-dimethylxanthine. Principal psychoactive agent in coffee, tea, guarana, and maté. Guarana has much more caffeine than coffee, by volume of plant material. 

Theobromine. Principal psychoactive agent in chocolate. 3,7-dimethylxanthine. About 12% of ingested caffeine is metabolized into theobromine by the liver, so coffee also causes more or less the same effects, in addition to its own stimulant effects, since there is much more caffeine in coffee than theobromine in chocolate.
