Sex differences in gallbladder bile acid composition and hepatic steroid 12 alpha-hydroxylase activity in hamsters.

Journal of Lipid Research, 1983
The gallbladder bile acid composition and the activity of the hepatic steroid 12 alpha-hydroxylase were determined in male and female hamsters. Cholic acid, chenodeoxycholic acid, and deoxycholic acid were the major bile acids in both sexes; in addition,

Does ursodeoxycholic acid change the proliferation of the colorectal mucosa? A randomized, placebo-controlled study [PDF]

, 2003
Background: In animal models ursodeoxycholic acid (UDCA) showed a chemoprotective effect against colon cancer. To explain this, a reduced proliferation of the colorectal mucosal proliferation was suggested.

Epimerization of chenodeoxycholic acid to ursodeoxycholic acid by human intestinal lecithinase-lipase-negative Clostridia.

Journal of Lipid Research, 1981
Six strains of lecithinase-lipase-negative Clostridia, isolated from human feces, were capable of oxidizing chenodeoxycholic acid to 3 alpha-hydroxy-7 keto-5 beta-cholanoic acid and of epimerizing it to ursodeoxycholic acid.

The Role of Bile in the Regulation of Exocrine Pancreatic Secretion [PDF]

, 1992
As early as 1926 Mellanby (1) was able to show that introduction of bile into the duodenum of anesthetized cats produces a copious flow of pancreatic juice.

Synthesis of 11, 12-2H2- and 11, 12-3H2-labeled chenodeoxycholic and lithocholic acids

Journal of Lipid Research, 1976
Deuterium- and tritium-labeled chenodeoxycholic acid and lithocholic were prepared by catalytic reduction of their respective Δ11 derivatives. Structures of the intermediates and their isotopic purity were verified by chemical ionization and electron ...

Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

Angewandte Chemie, EarlyView.
The human metabolism has been investigated for several millennia. The metabolome is known for a high complexity due to a large number of different metabolites that are present at different concentrations. Metabolomics has been developed as a field to investigate the entire human metabolome and to elucidate disease development mechanisms.

Hepatic 3-hydroxy-3-methylglutaryl coenzyme A reductase activity and biliary lipid composition in man: relation to cholesterol gallstone disease and effects of cholic acid and chenodeoxycholic acid treatment

Journal of Lipid Research, 1981
The present work was undertaken in order to study whether or not there is a relation between hepatic HMG CoA reductase, hepatic cholesterol concentration, and biliary lipid composition.

Dietary N-3 polyunsaturated fatty acids decrease biliary cholesterol saturation in gallstone disease [PDF]

, 1992
Because fatty acid composition of biliary phospholipids influences cholesterol secretion into bile, we investigated whether replacement of n-1 monounsaturated or n-6 polyunsaturated fatty acids with n-3 polyunsaturated fatty acids in biliary ...

pH-Solubility relations of chenodeoxycholic and ursodeoxycholic acids: physical-chemical basis for dissimilar solution and membrane phenomena.

Journal of Lipid Research, 1980
We examined by titration the electrochemical properties, apparent pK (pK'a), precipitation pH, and undissociated bile acid solubilities of chenodeoxycholic acid and its 7 beta epimer, ursodeoxycholic acid and their glycine conjugates as functions of a ...
