Slow metabolizer of caffeine
Webb29 sep. 2013 · You see, the CYP1A2 gene tells your liver to make one of two enzymes: CYP1A2 fast or CYP1A2 slow. Now, here's where it gets interesting. If you have the gene that makes the fast version of CYP1A2, each time you drink caffeinated coffee, your body processes and eliminates the caffeine from your bloodstream very quickly. WebbAs such, either polymorphism can be used to identify fast or slow metabolizers of caffeine. For rs2472300, GG corresponds to fast metabolizers, whereas GA and AA are considered slow metabolizers. For rs762551, AA corresponds to fast metabolizers, whereas AC and CC are considered slow metabolizers.
