3b,7b,12a-Trihydroxy-5a-Cholanoic acid
3b,7b,12a-Trihydroxy-5a-Cholanoic acid is a bile acid present in the urine of healthy humans, predominantly found in the glycine conjugate fraction (PMID 864325 ). Bile acids are steroid acids found predominantly in bile of mammals. The distinction between different bile acids is minute, depends only on presence or absence of hydroxyl groups on positions 3, 7, and 12.
