Taurochenodeoxycholic acid is a bile acid formed in the liver of most species, including humans, by conjugation of chenodeoxycholic acid with taurine.^[1] It is secreted into bile and then into the intestine.^[2] It is usually ionized at physiologic pH. However, although it can be crystallized as the sodium salt.

It acts as a detergent to solubilize fats in the small intestine and is itself absorbed by active transport in the terminal ileum.^[3]

It is used as a cholagogue and choleretic.

Substantial evidence indicates that high circulating bile acids promote colon cancer risk.^[4]^[5] In a prospective study, positive associations were observed between prediagnostic plasma levels of seven conjugated bile acid metabolites, including taurochenodeoxycholic acid, and colon cancer risk.^[4]
