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

open access: yesJournal 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 ...

Effect of phospholipids and bile acids on cholesterol nucleation time and vesicular/micellar cholesterol in gallbladder bile of patients with cholesterol stones [PDF]

open access: yes, 1993
Supersaturation and rapid nucleation of cholesterol in bile are of key importance in the pathogenesis of cholesterol gallstones. While the effects of bile acids and phospholipids on cholesterol saturation of bile have been extensively studied, their ...

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

open access: yesJournal 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.

Taurine/chenodeoxycholic acid ratio as a potential serum biomarker for low vitamin B<sub>12</sub> levels in humans. [PDF]

open access: yesBr J Nutr
Deficiency of vitamin B-12 (B-12 or cobalamin), an essential water-soluble vitamin, leads to neurological damage, which can be irreversible and anaemia, and is sometimes associated with chronic disorders such as osteoporosis and cardiovascular diseases ...

Study on the Factors Influencing the Extraction of Chenodeoxycholic Acid from Duck Bile Paste by Calcium Salt Method [PDF]

open access: yes, 2018
New extraction technology of chenodeoxycholic acid from duck bile paste by calcium salt was investigated. The optimum conditions of extraction were determined by orthogonal experimental design.

The economy of the enterohepatic circulation of bile acids in the baboon. 2. Regulation of bile acid synthesis by enterohepatic circulation of bile acids.

open access: yesJournal of Lipid Research, 1984
Isotope dilution within bile acid pools and radiochemical assessment of cholesterol oxidation to bile acids were methods used to measure short-term feedback regulation of bile acid synthesis in baboons with controlled enterohepatic circulations ...

Bile acid formation in man: metabolism of 7α-hydroxy-4-cholesten-3-one in bile fistula patients

open access: yesJournal of Lipid Research, 1973
7α-Hydroxy-4-cholesten-3-one is thought to be an intermediate in human bile acid synthesis. This conclusion is based on in vivo experiments in animals and on in vitro studies in which homogenates of animal and human livers were used. To further establish

Interaction of chenodeoxycholic acid with cholesterol in a model system studied by spin label probe method

open access: yes, 2014
Interaction of cholesterol which is an essential structural component of animal cell membranes that is required to establish proper membrane permeability and fluidity and the bile chenodeoxycholic acid which significantly increased serum total ...

Bile acid synthesis in HepG2 cells: effect of cyclosporin

open access: yesJournal of Lipid Research, 1994
The hypothesis that cyclosporin specifically affects the pathway of bile acid synthesis that begins with 27-hydroxylation of cholesterol was evaluated in HepG2 cells, which synthesize chenodeoxycholic acid and cholic acid from endogenous 7 alpha ...
