Glycochenodeoxycholic acid sodium is primarily used in medical and biochemical research as a bile acid derivative. It plays a significant role in studying bile acid metabolism and its impact on liver and digestive health. This compound is often utilized in experimental models to investigate cholestasis, a condition where bile flow from the liver is impaired. Additionally, it is employed in cell culture studies to examine its effects on cellular membranes and signaling pathways. Its ability to solubilize lipids makes it valuable in formulations for drug delivery systems, particularly for enhancing the absorption of poorly soluble drugs. In diagnostic applications, it aids in assessing liver function and bile acid-related disorders.
