Steroids 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 کاملSynthesis and characterization of polyurethanes made from copolymers of epoxidized natural oil and tetrahydrofuran.
Polyols were synthesized from epoxidized natural oils and tetrahydrofuran through ring opening copolymerization catalyzed by Lewis acid. The properties of these polyols depend on the type of natural oils as well as the reaction conditions (monomer concentration, catalyst amount, reaction temperature and reaction time). These polyols were evaluated as a raw material for making polyurethane (PU) ...
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,...
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 ...
