Cholic acid is a bile acid, a white crystalline substance insoluble in water (soluble in alcohol and acetic acid), with a melting point of 200-201 °C. Salts of cholic acid are called cholates. Cholic acid, along with chenodeoxycholic acid, is one of two major bile acids produced by the liver where it is synthesized from cholesterol. Of the two major bile acids, cholate derivatives represent approximately eighty percent of all bile acids. These derivatives are made from cholyl-CoA, which forms a conjugate with either glycine, or taurine, yielding glycocholic and taurocholic acid respectively.
