Bile 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 کاملIS BILE SCOLECIDAL?
Spillage of scoleces is a major problem in surgery of hydatid cysts, because each of them may develop into a new cyst if it settles on a suitable site such as the peritoneum. Many surgeons believe that scoleces in ruptured hydatid cysts of the liver containing bile are not able to develop new cysts, because bile kills thein. In order to prove this idea, the viability of scoleces in such cys...
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 کاملOccurrence of bile alcohols in the bile of a patient with cholestasis.
Considerable amounts (6.0 mumol/ml of bile) of bile alcohols were found in the bile of a patient with cholestasis due to gallstones in a common bile duct. Acid hydrolysis of the bile salts followed by chromatographic separation yielded three bile alcohols, which were identified as 26,27-dinor-5 beta-cholestane-3 alpha,7 alpha,12 alpha,24,25-pentol, 24-methyl-26,-27-dinor-5 beta-cholestane-3 alp...
