Biosynthesis of bile acids from cholesterol

WebCYP27A1 is a key enzyme in bile acid synthesis; it catalyzes the first step in the normal oxidation of the steroid side chain, converting cholesterol, as well as other 7α-hydroxylated cholesterol metabolites, into 27-oxygenated steroids (Fig. 1). In its absence, biosynthesis of bile acids (especially chenodeoxycholic acid, CDCA) is reduced. WebJun 1, 2024 · Of the two major pathways of bile acid synthesis in the liver, the foremost role of the acidic (alternative) pathway is to generate and control the levels of regulatory oxysterols that help control cellular cholesterol and lipid homeostasis.
