Deoxycholic acid degradation by a Pseudomonas species. Acidic intermediates from the initial part of the catabolic pathway

摘要

pThe microbial catabolism of deoxycholic acid by a Pseudomonas species was studied, and three acidic products were isolated as their methyl esters. Evidence is presented that the compounds are methyl 3 alpha,12 alpha-dihydroxy-23,24-dinor-5 beta-cholan-22-oate, methyl 12 alpha-hydroxy-3-oxo-5 beta-cholan-24-oate and methyl 12 alpha-hydroxy-3-oxo-23,24-dinor-5 beta-cholan-22-oate./p
