Goose deoxycholic acid, also known as 3 α, seven α- Dihydroxy-5 β- Bile-24-carboxylic acid is a white crystalline substance that is insoluble in water but soluble in ethanol and acetic acid. Its melting point is between 165-167 ° C. Goose deoxycholic acid and bile acid are the two main components of bile produced by the liver. The main function is to reduce the saturation of cholesterol in the bile. After taking CDCA, the lipids in the majority of patients return to a micro colloidal state, and cholesterol is in an unsaturated state, thereby dissolving and shedding cholesterol in the stones. This product is currently one of the largest drugs used to treat gallstones in the world, and it is also a raw material for synthesizing ursodeoxycholic acid (UDCA) and other steroid compounds.
