The bile-salt-dependent lipase from human milk, which catalyzes the hydrolysis of the water-soluble substrate 4-nitrophenyl acetate and the water-insoluble substrate tributyrin, is competitively inhibited by phenyl boronic acid. This inhibitor does not interfere with the interaction of lipase either with the siliconized glass beads/water interface or ...

The ionic behavior of fatty acids solubilized by bile salts
Journal of Colloid and Interface Science, 1970Abstract The influence of different bile salts on the ionic behavior of oleic acid, in the presence and absence of salt, has been investigated symmetrically by a titration study. The effect of ionic strength, degree of ionization, and the ratio oleic acid bile salt, on the composition and size of the mixed micelles in these systems has been ...

Biotechnology Letters, 2015
Changes of bile salt tolerance, morphology and amount of bile acid within cells were studied to evaluate the exact effects of bile salt hydrolase (BSH) on bile salt tolerance of microorganism.The effect of BSHs on the bile salt tolerance of Lactococcus lactis was examined by expressing two BSHs (BSH1 and BSH2). Growth of L.

Human OATP1B1 (SLCO1B1) transports sulfated bile acids and bile salts with particular efficiency
Toxicology in Vitro, 2018Human OATP1B1 is highly expressed at the basolateral membrane of the hepatocyte. It plays an important role in the sodium-independent transport of bile acids and bile salts and contributes to the systemic clearance of many drugs. In this study, the interaction of at least one representative of all major chemical classes of bile acids and bile salts ...

Liquid solubilization dynamics: Oleic acid in bile salt
Journal of Colloid and Interface Science, 1982Abstract The solubilization dynamics of oleic acid by aqueous sodium taurodeoxycholate solutions at 37°C does not conform to previous resistance in series models involving diffusion and interfacial steps. This is especially true as the ionic strength of the aqueous solution is increased by adding NaCl or by increasing the taurodeoxycholate ...

Micellar behaviour in solutions of bile-acid salts
Kolloid-Zeitschrift & Zeitschrift für Polymere, 1971From the vapour-pressure values for aqueous solutions of sodium cholate, desoxycholate and dehydrocholate measured by a thermistor method the osmotic coefficients, the activity of water and the mean activity of the bile salts have been calculated. In the case of sodium cholate and desoxycholate these quantities were found to vary with concentration in ...

Cholesterol Monohydrate Dissolution in the Presence of Bile Acid Salts
Crystal Growth & Design, 2013The molecular-level dissolution of cholesterol monohydrate single crystal (001) surfaces was systematically investigated in aqueous solutions of chenodeoxycholate (CDC) and ursodeoxycholate (UDC) u...

Effect of bile salts on amino acid transport by rabbit intestine
American Journal of Physiology-Legacy Content, 1975The effect of bile salts on alanine absorption across four regional sites of rabbit intestine was examined using an in vivo single-pass perfusion technique. Na-deoxycholate at a concentration of 3 mM reduced alanine absorption across all levels of the intestine, and a higher concentration (10 mM) of Na-taurodeoxycholate (TDC) caused only a minimal ...

RELATION OF FATTY ACIDS AND BILE SALTS TO THE FORMATION OF GALLSTONES
Archives of Internal Medicine, 1940In a previous report1some of the chemical differences between the bile of certain domestic animals and that of human beings were discussed. By fractionating the bile of the dog and sheep, animals in which gallstones are not formed ordinarily, it was observed that the cholesterol solvent capacity of the bile could be isolated in the saponifiable or ...

Effects of oleic acid and bile salts on canine villous motility
Life Sciences, 1989The effects on canine villous motility of mucosal Tyrodes solution containing oleic acid (10 mM) and/or either taurocholic or cholic acid (15 mM) in the presence or absence of IV atropine (1 mg/kg) was used to assess the neural mediation of the effects of luminal nutrients. Villous motility was measured over 12 min periods by in vivo videomicroscopy of
