Chemical synthesis of 5beta-cholestane-3alpha, 7alpha, 24, 25-tetrol and its metabolism in the perfused rabbit liver. 1978

T Kuramoto, and B I Cohen, and M A Rothschild, and D A Donor, and E H Mosbach

5beta-[G-3H]Cholestane-3alpha, 7alpha, 24xi, 25-tetrol (IV) was synthesized via dehydration and peroxidation of 5beta-[G-3H]cholestane-3alpha, 7alpha, 25-triol. Following perfusion of the labeled compound in the isolated rabbit liver, the bile alcohol and bile acid metabolites secreted into the bile were identified by a combination of thin layer chromatography, gas-liquid chromatography, and gas-liquid chromatography/mass spectrometry. The following bile alcohols were tentatively identified: 5beta-cholest-23-ene-3alpha, 7alpha, 25-triol, 5beta-cholest-25-ene-3alpha, 7alpha, 12alpha, 24xi-tetrol, and 5beta-cholestane-3alpha, 7alpha, 12alpha, 24xi, 25-pentol. The amount of administered tetrol recovered unchanged ranged from 1 to 88%. Cholic acid was the major product, but limited amounts of chemodeoxycholic acid were also formed. The 24-hydroxyl group in the steroid side chain did not prevent 12alpha-hydroxylation.

D002635 Chenodeoxycholic Acid A bile acid, usually conjugated with either glycine or taurine. It acts as a detergent to solubilize fats for intestinal absorption and is reabsorbed by the small intestine. It is used as cholagogue, a choleretic laxative, and to prevent or dissolve gallstones.

D002777 Cholestanols Cholestanes substituted in any position with one or more hydroxy groups. They are found in feces and bile. In contrast to bile acids and salts, they are not reabsorbed. Bile Alcohol,Bile Alcohols,Hydroxycholestane,Hydroxycholestanes,Alcohol, Bile,Alcohols, Bile
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001646 Bile An emulsifying agent produced in the LIVER and secreted into the DUODENUM. Its composition includes BILE ACIDS AND SALTS; CHOLESTEROL; and ELECTROLYTES. It aids DIGESTION of fats in the duodenum. Biliary Sludge,Sludge, Biliary
D001647 Bile Acids and Salts Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones. Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
