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.
