Uses
3α,7α,12α-Trihydroxycoprostanic Acid is a precursor of Cholic Acid (C432600), it undergoes side chain oxidation during the synthesis of bile acids. It was found that Zellweger’s syndrome patients have abnormal mitochondrial structure, the organelle that is responsible for the side chain oxidation, and as a consequence, excess amounts of 3α,7α,12α-Trihydroxycoprostanic Acid.
Definition
ChEBI: A steroid acid that is 5beta-cholestan-26-oic acid which is substituted by hydroxy groups as the 3alpha, 7alpha, and 12alpha positions.
General Description
Trihydroxycholestanoic acid (THCA) is an oxidative metabolite of cholesterol and a precursor to bile acids. Very long-chain acyl-CoA synthetase (VLCS) associated with endoplasmic reticulum and peroxisomes activates THCA, the C27 bile acid intermediate.
Biochem/physiol Actions
Trihydroxycholestanoic acid (THCA) and dihydroxycholestanoic (DHCA) accumulation is observed in Zellweger syndrome and cholestatic liver disease. The synthesis of (25R)-isomer of DHCA and THCA is favored by mitochondrial 27-hydroxylase.
