Cholic acid (also known as 3α,7α,12α-trihydroxy-5β-cholan-24-carboxylic acid, 3α,7α,12α-trihydroxy-5β-cholan-24-oic acid) is bile The main component of acid, insoluble in water, soluble in ethanol and acetic acid, solid as white crystals, its salts are called cholates (English: cholates). Chole acid and chenodeoxycholic acid are the two major components of bile acids, which are produced by the liver metabolizing cholesterol. The concentrations of these two major bile acids in the human body are roughly equal. The derivatives of cholic acid are mainly generated by cholic acid-coenzyme A (cholyl-CoA), in which CoA can be exchanged with glycine or taurine to generate glycocholic acid or taurocholic acid.
