Bile salts of the green turtle Chelonia mydas (L.)

摘要: 1. Bile salts of the green turtle Chelonia mydas (L.) were analysed as completely possible. 2. They consist taurine conjugates 3 alpha, 7 12 22 xi-tetrahydroxy-5 beta-cholestan-26-oic acid (tetrahydroxysterocholanic acid) and alpha xi-trihydroxy-5 acid, with minor amounts alpha-trihydroxy-5beta-cholan-24-oic (cholic acid), 3alpha, alpha-dihydroxy-5beta-cholan-24-oic (deoxycholic possibly other bile acids. 3. Cholic deoxycholic represent first known examples acids common to chelonians animal forms: they may indicate independent evolution in C24 4. The discovery a 7-deoxy C27 is evidence that or their have an enterohepatic circulation.
