WebThe most important enzyme system of phase I metabolism is cytochrome P-450 (CYP450), a microsomal superfamily of isoenzymes that catalyzes the oxidation of many drugs. The electrons are supplied by NADPH–CYP450 reductase, a flavoprotein that transfers electrons from NADPH (the reduced form of nicotinamide adenine dinucleotide phosphate) to … WebCytochrome P450 enzymes are primarily found in liver cells but are also located in cells throughout the body. While a large body of knowledge exists on the role of CYP450s in xenobiotic metabolism, recent studies have begun to reveal the endogenous functions carried out by this important superfamily of enzymes. curious george sock monkey https://jgson.net
