Web1. Introduction. Cytochrome P450 (CYP) enzymes are a diverse group of heme monooxygenases that have been actively studied in conjunction with their crucial roles in metabolism or biotransformation of drugs and xenobiotics, but also in the biosynthesis of sterols, fatty acids, eicosanoids, vitamins, etc. [1,2].CYP enzymes play a prominent role … Human CYPs are primarily membrane-associated proteins located either in the inner membrane of mitochondria or in the endoplasmic reticulum of cells. CYPs metabolize thousands of endogenous and exogenous chemicals. Some CYPs metabolize only one (or a very few) substrates, such as CYP19 (aromatase), while others may metabolize multiple substrates.
