WebThe conversion from cholesterol to cholic and chenodeoxycholic acids involves four steps: 1) the initiation of synthesis by 7alpha-hydroxylation of sterol precursors, 2) further modifications to the ring structures, 3) side-chain oxidation and shortening (cleavage) by three carbons, and 4) conjugation of the bile acid with taurine or glycine. WebNov 4, 2024 · Abstract. Primary bile acids are the end product of cholesterol catabolism synthesized in the liver and excreted into bile. Secondary bile acids are derived after modifications of primary bile acids by intestinal microbiota.

WebThe primary digestive function of bile is to aid in the dispersion and digestion of fat in the lumen of the small intestine. Bile is formed initially in the hepatocyte (liver cell), and the rate of formation is dependent primarily on the rate at which bile acids are secreted into the bile channels, or canaliculi. A portion of the bile flow, however, is related to factors other than … WebIntroduction.

"WebHepatic synthesis of BAs accounts for 0.2-0.6 g/day with an overall BA pool of about 3 g in the liver and intestine. More than 95% of the secreted BAs are reabsorbed through active absorption at the terminal ileum by the specific bile acid transporter apical sodium-dependent bile acid transporter (ASBT) and passive absorption in the colon.
