The structure of the bile acids in serum of infants with coprostanic acidemia was further investigated. The identity of 3 alpha-hydroxy-5 beta-cholestan-26-oic acid and 3 beta-hydroxy-5-cholesten-26-oic acid was confirmed. The biosynthesis of the 3 alpha, 7 alpha, 12 alpha-trihydroxy-5 beta-C29 dicarboxylic bile acid does not start from beta-sitosterol.
