Bile Acids. Xix. Metabolism of Lithocholic Acid-24-14c in the Rat.
Although the principal bile acid formed from cholesterol in the rat is cholic acid (2, 3), Siperstein et al. (4) reported the formation of a small amount of lithocholic acid. Bergstriim, Sjovall, and Voltz (5) reported that lithocholic acid is not converted to cholic acid, but transformed into several unidentified acids. Subsequently, we identified P-muricholic acid (3a, S/3,7/3-trihydroxy-5/3-...

گوشت قرمز یکی از مهم ترین فرآورده های دامی در تأمین پروتئین و انرژی می باشد که در حمل ویتامین های محلول در چربی نیز حائز اهمیت می باشد. انسان مانند سایر مهره داران اسید های چرب ضروری (لینولئیک و آلفا لینولنیک) مورد نیاز خود از طریق غذا تأمین می نماید. اسید های چرب ضروی پیش ساز اسید های چرب غیر اشباع با چند پیوند دوگانه هستند. اسید لینولنیک پیش ساز اسیدهای چرب امگا 3 و اسید لینولئیک نیز پیش ساز ...
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 کاملThe formation of lithocholic acid, chenodeoxycholic acid and alpha- and beta-muricholic acids from cholesterol incubated with rat-liver mitochondria.
1. When rat-liver mitochondria were incubated with [4-(14)C]cholesterol in the presence of a soluble supernatant fraction, various steroids more polar than cholesterol were formed. These included 3beta-hydroxycholest-5-en-26-oic acid, 3beta-hydroxychol-5-enoic acid, lithocholic acid, chenodeoxycholic acid and alpha- and beta-muricholic acids. 2. All the radioactive C(24) bile acids recovered we...
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. ...
