CC -!- FUNCTION: A cytochrome P450 monooxygenase involved in the metabolism of
CC various endogenous substrates, including fatty acids, steroid hormones
CC and vitamins. Mechanistically, uses molecular oxygen inserting one
CC oxygen atom into a substrate, and reducing the second into a water
CC molecule, with two electrons provided by NADPH via cytochrome P450
CC reductase (NADPH--hemoprotein reductase). Catalyzes the hydroxylation
CC of carbon-hydrogen bonds. Exhibits high catalytic activity for the
CC formation of hydroxyestrogens from estrone (E1) and 17beta-estradiol
CC (E2), namely 2-hydroxy E1 and E2. Metabolizes cholesterol toward 25-
CC hydroxycholesterol, a physiological regulator of cellular cholesterol
CC homeostasis. May act as a major enzyme for all-trans retinoic acid
CC biosynthesis in the liver. Catalyzes two successive oxidative
CC transformation of all-trans retinol to all-trans retinal and then to
CC the active form all-trans retinoic acid. Primarily catalyzes
CC stereoselective epoxidation of the last double bond of polyunsaturated
CC fatty acids (PUFA), displaying a strong preference for the (R,S)
CC stereoisomer. Catalyzes bisallylic hydroxylation and omega-1
CC hydroxylation of PUFA. May also participate in eicosanoids metabolism
CC by converting hydroperoxide species into oxo metabolites (lipoxygenase-
CC like reaction, NADPH-independent). Plays a role in the oxidative
CC metabolism of xenobiotics. Catalyzes the N-hydroxylation of
CC heterocyclic amines and the O-deethylation of phenacetin. Metabolizes
CC caffeine via N3-demethylation. {ECO:0000250|UniProtKB:P05177}.
