Stero-Bile Acids and Bile Sterols
In a previous paper (XLVI of this series), the isolation of cyprinol and other three new bile sterols from the alkaline hydrolyzate of carp bile was reported. Also it was suggested that the chemical constitution of one of these new bile sterols would correspond to 3ƒ¿, 7ƒ¿, 12ƒ¿-trihydroxy-26, 27-epoxycholestane and the natural form of this new bile sterol might be 3ƒ¿,7ƒ¿,12ƒ¿,26,27-pentahydro...
متن کاملBiliary bile acids, bile alcohols, and sterols of Alligator mississippiensis.
Bile from Alligator mississippiensis was found to contain a mixture of more than twenty bile acids, bile alcohols, and neutral sterols. Bile acids and bile alcohols were purified by reversed-phase high performance liquid chromatography and thin-layer chromatography. Concentrations were measured by gas-liquid chromatography on 1% HiEFF-8BP and identifications were made by mass spectrometry. The ...
متن کاملRegulatory effects of dietary sterols and bile acids on rat intestinal HMG CoA reductase.
The specific activity (concentration) of microsomal HMG CoA reductase of intestinal crypt cells was studied in rats fed sterols and bile acids, either singly or in combination. It was found that the basal activity of the reductase was not suppressed by the administration of relatively large amounts of bile acid (taurocholate or taurochenodeoxycholate). Bile acids reduced the specific activity o...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولSterols 5. Bile Acids and Alcohols Structures, Occurrence and Biochemistry
The bile acids (mainly C24 but also C27) are the end products of cholesterol catabolism in animals, the main functions of which are to act as powerful detergents or emulsifying agents in the intestines to aid the digestion and absorption of fatty acids, monoacylglycerols and other fatty products and to prevent the precipitation of cholesterol in bile. Very many different bile acids and alcohols...
