Abstract
An enzyme assay was developed to measure the conversion of the bile acid precursor, 3alpha, 7alpha, 12alpha-trihydroxy-5beta-cholestan-26-oic acid (THCA), into cholic acid using homogenates of human liver biopsies. The average rate of metabolism of THCA into cholic acid was found to be 3.9 +/- 0.5 (+/- 1 SD) pmoles of cholic acid formed/mg liver/minute in twelve normal liver biopsies. This assay system can be used to determine if the syndrome of neonatal cholestasis associated with a metabolic block in the conversion of THCA into cholic acid is transmitted as a genetic trait.
