Common Nameisocholic acid
DescriptionIsocholic acid is a bile acid metabolite belonging to the chemical class of steroid acids. Its chemical structure is characterized by a steroid backbone with hydroxyl groups at specific positions, influencing its solubility and biological activity. Isocholic acid is primarily formed in the liver through the reduction of 7 alpha,12 alpha-dihydroxy-3-keto-5 beta-cholanoic acid by specific enzymes localized in the cytosol, which exhibit a preference for unconjugated substrates (PMID:3778926 ). This enzymatic pathway is distinct from those that produce other iso-bile acids, highlighting the stereospecific nature of the reduction process (PMID:3778926 ). Under normal redox conditions, the conversion of 3-oxo-cholic to cholic acid occurs without the formation of isocholic acid, indicating a regulated metabolic pathway (PMID:3468121 ). Furthermore, studies have examined the effects of isocholic acid and its epimeric forms on bile flow, lipid secretion, and bile acid synthesis, demonstrating its potential influence on hepatic functions (PMID:3715368 ). Overall, isocholic acid plays a role in bile acid metabolism, contributing to the complex interplay of bile acids in digestion and lipid absorption.
