WebApr 5, 2024 · Bile acid biosynthesis and circulation. Primary bile acids (BAs; e.g., cholic acid [CA] and chenodeoxycholic acid [CDCA]) are synthesized by hepatocytes via two … WebBile acids are hydroxylated steroids, synthesized in the liver from cholesterol. Peroxisomal enzymes assist in the hepatic biosynthesis of BAs. Bile acids are normally conjugated in the liver to the amino acids, Gly and Tau, or sulfate. The active transport of BAs across canalicular membranes of hepatocytes is a primary driving force for bile flow.
