| allocholic acid | An allo-bile acid that is 5alpha-cholan-24-oic acid bearing three alpha-hydroxy substituents at position 3, 7 and 12. | allocholic acid |
| chenodeoxycholic acid | A dihydroxy-5beta-cholanic acid that is (5beta)-cholan-24-oic acid substituted by hydroxy groups at positions 3 and 7 respectively. | chenodeoxycholic acid |
| cholic acid | A bile acid that is 5beta-cholan-24-oic acid bearing three alpha-hydroxy substituents at position 3, 7 and 12. | cholic acid |
| deoxycholic acid | A bile acid that is 5beta-cholan-24-oic acid substituted by hydroxy groups at positions 3 and 12 respectively. | deoxycholic acid |
| hyodeoxycholic acid | A member of the class of 5beta-cholanic acids that is (5beta)-cholan-24-oic acid substituted by alpha-hydroxy groups at positions 3 and 6. | hyodeoxycholic acid |
| lithocholic acid | A monohydroxy-5beta-cholanic acid with a alpha-hydroxy substituent at position 3. It is a bile acid obtained from chenodeoxycholic acid by bacterial action. | lithocholic acid |
| muricholic acid | A group of trihydroxy-5beta-cholanic acids that are the 6,7-diastereoisomers of 3alpha,6,7-trihydroxy-5beta-cholan-24-oic acid. | muricholic acids |
| ursocholic acid | A bile acid that is 5beta-cholan-24-oic acid bearing three hydroxy substituents at positions 3alpha, 7beta and 12alpha. | ursocholic acid |
| ursodeoxycholic acid | A bile acid found in the bile of bears (Ursidae) as a conjugate with taurine. Used therapeutically, it prevents the synthesis and absorption of cholesterol and can lead to the dissolution of gallstones. | ursodeoxycholic acid |
