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 کاملStudies on bile acids: The microquantitative separation of cellular bile acids by gas-liquid chromatography.
1. A method is described for the quantitative isolation of bile acids from cellular material. Homogenates of rat liver are freeze-dried and extracted exhaustively with 95% (v/v) ethanol containing 0.1% (v/v) of aq. ammonia (sp.gr. 0.88) and purified by anion-exchange chromatography on Amberlyst A-26. 2. The extracted bile acid conjugates are subjected to either of two hydrolytic procedures, one...
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 کاملSeparation of bile acids of rat bile by thin-layer chromatography.
The common bile acids of rat bile (chenodeoxycholic, hyodeoxycholic, cholic, alpha-muricholic, and beta-muricholic acids) are completely separated by a new thin-layer chromatographic system.
متن کاملSeparation of Amino Acids by Paper Chromatography
Chromatography is a common technique for separating chemical substances. The prefix “chroma,” which suggests “color,” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment, chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate...
