Deoxycholic acid (DCA, CAS: 83-44-3) is a secondary bile acid with the chemical formula C₂₄H₄₀O₄ and molecular weight 392.58 g/mol. Formed through 7α-dehydroxylation of primary bile acids (e.g., cholic acid) by gut microbiota, it holds dual significance in metabolic regulation and medical aesthetics. As the first FDA-approved injectable lipolytic drug (Kybella®, 2015), its serum levels (normal range: 0.5-5.0 μmol/L) are recognized in the 2023 Gastroenterology guidelines as key indicators of gut-liver axis function.
