描述
Cholestane-3,7,12,24,25-pentol is the major bile alcohol identified in urine from healthy humans, both in children and adults. Bile alcohols have been found to be present as minor components in the bile and urine in healthy subjects. Bile alcohols are end products for cholesterol elimination as well as major biliary constituents; in mammals, cholesterol is metabolized by additional enzymes that ultimately transform it to bile acids. Bile alcohols are preferentially excreted as glucuronides into the urine, which constitute about 10% of total bile acids. The excretion of glucuronidated bile alcohols in urine is suggested to reflect an alternative metabolism of intermediates in the normal biosynthesis of bile acids. Patients with the rare inherited sterol storage disease, cerebrotendinous xanthomatosis, accumulation bile alcohols in bile and feces.(PMID: 6726087, 6548247, 11718684) [HMDB]
