A group of steroid acids present in bile. In humans, the commonest is cholic acid (C24H40O5), which is conjugated by its carboxyl group to the amino groups of the amino acids glycine and taurine. The bile acids are emulsifiers for fats and fat-soluble vitamins, thus promoting their absorption by the small intestine.
