Metabolite Identification

Common Name

18-Hydroxyarachidonic acid

Description

(18R)-Hydroxyarachidonate is a substrate for CYP4F8 or leukotriene-B4 20-monooxygenase (EC 1.14.13.30). This enzyme hydroxylates arachdonic acid (20:4n-6) to (18R)-hydroxyarachidonate in the endoplasmic reticulum. This reaction is irreversible. CYP4F8 is a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum and functions as a 19-hydroxylase of prostaglandins in seminal vesicles. In particular, CYP4F8 catalyzes the 2-hydroxylation of PGH1 and PGH2, which will lead to biosynthesis of the two main PGs of human seminal fluid, (19R)-hydroxy-PGE1 and (19R)-hydroxy-PGE2 (PMID: 10791960 ). 18-Hydroxyarachidonic acid is an intermediate in eicosanoid metabolism.
