Glycoobeticholic acid is a structurally distinct impurity of obeticholic acid, characterized by the presence of a glycosyl moiety. This modification introduces a hydrophilic functional group, altering its physicochemical properties. Its chemical structure is closely related to the parent drug, with the glycosylation occurring at a specific position. It serves as a critical reference standard for HPLC analysis.
