Ursocholic acid (3α,7β,12α-trihydroxy-5β-cholan-24-oic acid) is a stereoisomer of cholic acid and a bile acid used primarily in biochemical research. It is employed in studies of bile acid metabolism, transport mechanisms, and enterohepatic circulation. Researchers utilize it to investigate the roles of bile acids in liver function, digestion, and potential interactions with bile acid receptors and transporters. Unlike ursodeoxycholic acid, it is not approved for clinical therapeutic use but may be explored in experimental models for hepatoprotective properties or liver disorder studies.
