Bile Acids and Steroids
In several mammalian species, i.e. rabbit, dog and man, deoxycholic acid is one of the main bile acids in the bile (1). In recent years evidence has accumulated that deoxycholic acid is formed from cholic acid during the enterohepatic circulation by the action of intestinal microorganisms. By the use of 24-@-labeled cholic acid this conversion has been demonstrated in rabbit and in man (2,3). B...
متن کاملSteroids Derived from Bile Acids
Derivatives of bile acids with substituents in Ring C have been described in the preceding papers of this series (l-6). It is the purpose of this paper to assign the probable stereochemical configurations for these compounds. As desoxycholic acid (I)l is a convenient reference compound, it will first be necessary to discuss briefly the spatial arrangement of certain portions of this bile acid. ...
متن کاملThe Estimation of Bile Acids in Bile
In a recent paper Foster and Hoop& (1) have described a rapid method for the estimation of bile acids in dog bile. The method depends on the fact that the two bile acids usually found in dog bile, viz. taurocholic and taurocholeic, on hydrolysis with alkali give taurine, which yields its nitrogen quantitatively in 4 minutes when shaken with HN02. Taurocholic and taurocholeic acids do not react ...

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,...
