<prompt> Which of the following isare bile acids -Cholic acidLithocholic acidDeoxychoiic acidAll of the above  <response>: Ans. is d i.e., All of the aboveo Primary bile acids are cholic acid and chenodeoxycholic acid, which are synthesized from cholesterol in liver. In the intestine some of the primary bile acids are converted into secondary bile acids, i.e., deoxycholic acid formed from cholic acid and lithocholic acid derived from chenodexoxycholic acid.o Glycine and taurine conjugates of these bile acids are called as bile salts. For example, cholic acid is a bile acid, and its glycine conjugate glycocholic acid is a bile salt.o Bile salts Sodium or potassium Amino acid glycine or taurine Bile acids Cholic acid or chenodeoxycholic acido So, Bile salts are : -Sodium glycine -f cholic acid Sodium-glyco-cholic acid sodium-glyco-cholateSodium taurine cholic acid Sodium-tauro-cholic acid Sodium-tauro-cholateSodium glycine chenodeoxycholic aicd Sodium-glyco-chenodeoxycholateSodium taurine chenodeoxycholic acid Sodium-tauro-chenodeoxycholateo Similarly potassiun bile salts are potassium-glycochoiate, potassium-taurocholate, potassium-glyco- chenodexoxycholate, and potassium-tauro-chenodexoxycholate.
