CYP2A6, CYP2E1, and CYP3A4 have been shown to play a role in caffeine. Most of the caffeine you ingest is metabolized by a CYP450 liver enzyme called “CYP1A2.” This means that the body uses CYP1A2 to “demethylate” caffeine molecules, transforming them into other substances, chiefly paraxanthine, which are ultimately excreted in the urine. While 3-N-demethylation is quantitatively the main oxidation pathway in human, 8-hydroxylation is the dominant metabolic pathway in rat. Due to its safety, favorable pharmacokinetic properties, and P450 isoform-selective metabolism, caffeine has great potential as a metabolic marker substance in both humans and rats, and as a more universal metabolic tool in the latter species. In contrast to mammals, theobromine was the predominant metabolite (paraxanthine in humans; theophylline in monkeys; 1, 3, 7-trimethyluric acid in rodents). The speed of this decline depends on your CYP1A2 gene, which controls an enzyme (also called CYP1A2) that is in charge of breaking down any caffeine that enters the body. The Gut Health Guidebook!

In male adult fly bodies, caffeine is degraded into 4 major metabolites: theobromine, M2, paraxanthine and theophylline. CYP1A2 localizes to the endoplasmic reticulum and its expression is induced by some polycyclic aromatic hydrocarbons (PAHs), some of which are found in cigarette smoke. The specific-targeted silencing of some CYP expression in sensory neurons leads to an alteration of caffeine perception, revealing the crucial role of these enzymes in chemoperceptive processes.
