Stero-Bile Acids and Bile Sterols
In a previous paper (XLVI of this series), the isolation of cyprinol and other three new bile sterols from the alkaline hydrolyzate of carp bile was reported. Also it was suggested that the chemical constitution of one of these new bile sterols would correspond to 3ƒ¿, 7ƒ¿, 12ƒ¿-trihydroxy-26, 27-epoxycholestane and the natural form of this new bile sterol might be 3ƒ¿,7ƒ¿,12ƒ¿,26,27-pentahydro...
متن کاملBile acids and bile alcohols of bullfrog1
Gallbladder bile of the bullfrog, R a m catesbezana was found to contain a number of minor bile acids and bile alcohols in unconjugated forms. The following bile acids and bile alcohols were identified by combined gas-liquid chromatography-mass spectrometry: cholic acid, allocholic acid, 3a,7a, 12a-trihydroxy-5a-cholestan-26-oic acid, 3a,7a, 12atrihydroxy-24-methyl-5~-cholestan-26-oic acid, 3a,...
متن کاملBiliary bile acids, bile alcohols, and sterols of Alligator mississippiensis.
Bile from Alligator mississippiensis was found to contain a mixture of more than twenty bile acids, bile alcohols, and neutral sterols. Bile acids and bile alcohols were purified by reversed-phase high performance liquid chromatography and thin-layer chromatography. Concentrations were measured by gas-liquid chromatography on 1% HiEFF-8BP and identifications were made by mass spectrometry. The ...
متن کاملNatural occurrence and chemical synthesis of bile alcohols, higher bile acids, and short side chain bile acids.
Both bile acids and bile alcohols, a subclass of steroids, are made from cholesterol as its major end metabolites by the liver of vertebrates. Their conjugates are the major constituents of the bile and possess a special function as an aid to intestinal lipid digestion and absorption. The most common naturally occurring bile acids in mammals, birds, most snakes, and various teleostean fishes, a...
متن کاملSterols 5. Bile Acids and Alcohols Structures, Occurrence and Biochemistry
The bile acids (mainly C24 but also C27) are the end products of cholesterol catabolism in animals, the main functions of which are to act as powerful detergents or emulsifying agents in the intestines to aid the digestion and absorption of fatty acids, monoacylglycerols and other fatty products and to prevent the precipitation of cholesterol in bile. Very many different bile acids and alcohols...
