<prompt> Which of the following isare bile acids?Cholic acidLithocholic acidDeoxycholic acidAll of the above  <response>: 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 conveed into secondary bile acids, i.e., deoxycholic acid formed from cholic acid and lithocholic acid derived from chenodexoxycholic acid. 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. Bile salts Sodium or potassium Amino acid glycine or taurine Bile acids Cholic acid or chenodeoxycholic acid So, Bile salts are : - Sodium glycine cholic acid Sodium-glyco-cholic acid sodium-glyco-cholate Sodium taurine cholic acid Sodium-tauro-cholic acid Sodium-tauro-cholate Sodium glycine chenodeoxycholic aicd Sodium-glyco-chenodeoxycholate Sodium taurine chenodeoxycholic acid Sodium-tauro-chenodeoxycholate o Similarly potassiun bile salts are potassium-glycocholate, potassium-taurocholate, potassium-glycochenodexoxycholate, and potassium-tauro-chenodexoxycholate.
