title: Identification of 5 beta-cholestane-3 alpha, 7 alpha, 12 alpha, 25, 26-pentol in cerebrotendinous xanthomatosis.
abstract: An unrecognized pentahydroxy bile alcohol has been isolated from the bile and feces of patients with cerebrotendinous xanthomatosis (CTX). Its structure, 5 beta-cholestane-3 alpha, 7 alpha, 12 alpha, 25, 26-pentol has been deduced by spectroscopic methods and confirmed by comparison with a synthetic analog.
