The main metabolic pathway for the bile acid intermediates di- and trihydroxycoprostanic acid is through peroxisomal ß-oxidation. Patients with either a peroxisome biogenesis defect or a specifically bile acid ß-oxidation defect accumulate these DHCA and THCA in blood and bile.
Measurement of DHCA and THCA in body fluids contributes to the diagnosis of such defects, both postnatal and prenatal.
