Glycochenodeoxycholic acid, also abbreviated as GDCA, is a bile salt formed in the liver from chenodeoxycholic acid and glycine, usually found as the sodium salt. It acts as a detergent to solubilize fats for absorption.[citation needed]

Positive associations were observed between prediagnostic plasma levels of seven different conjugated bile acid metabolites, including glycochenodeoxycholic acid, and colon cancer risk. These findings support experimental data suggesting that a high bile acid load promotes colon cancer.
