• 05:19, 2 September 2021 Dianagarnica talk contribs uploaded File:2016 Coffee- Health Effects .pdf (The main mechanism of action of caffeine is to antagonize adenosine receptors (with its A1 and A2A subtypes); a second- ary effect is the inhibition of phosphodiesterases, with the subsequent accumulation of cyclic adenosine monophosphate and an intensification of the effects of catecholamines. Coffee is metabolized in the liver by enzymes known as cytochrome P450 1A2 (CYP1A2). Caffeine effects translate, in most people, in a psychoactive response, which includes increased alertness and atten...)
