Glycochenodeoxycholic acid-d7 (sodium) is the deuterium labeled Glycochenodeoxycholic acid (sodium salt). Glycochenodeoxycholic acid sodium salt (Chenodeoxycholylglycine sodium salt) is a bile acid formed in the liver from chenodeoxycholate and glycine. It acts as a detergent to solubilize fats for absorption and is itself absorbed. Glycochenodeoxycholic acid sodium salt (Chenodeoxycholylglycine sodium salt) induces hepatocyte apoptosis[1][2].
