Muricholic acid

Muricholic acids are a group of bile acids found as one of the main forms in mice, which gives them their name, and at low concentrations in other species. They are detectable at low concentrations in human urine. The three major bile acids in germ-free mice are cholic, α-muricholic and β-muricholic acids. In conventional mice, ω-muricholic acid, and various sulphated forms are also found. Conjugation with taurine or glycine takes place in the liver before secretion.
