Search. User data Module. 1. The main caffeine catabolite produced in the liver is likely to be 1,3,7-trimethyluric acid (Roberts et al., 1994).The initial major step in caffeine (and paraxanthine) metabolism is demethylation at positions 3 and 7 by the microsomal oxidase CYP1A2 (Gu et al., 1992). Identification of the genes for the first two reactions of the C-8 oxidation pathway for caffeine metabolism (Fig. 2008) Relative CYP strengths metabolizing caffeine in human liver microsomes CYP1A2 is the primary enzyme responsible for caffeine metabolism in mice and humans - eliminating 87% of caffeine at normal concentrations in mice3. Industrial application: Pharmaceutical two new metabolites in caffeine and related purine human urine. 25.
