Taurochenodeoxycholic acid is primarily used in research settings to study bile acid metabolism and its role in digestive processes. It serves as a key compound in understanding the mechanisms of bile acid synthesis, transport, and signaling pathways in the liver and intestines. Additionally, it is utilized in experimental models to investigate its potential therapeutic effects in liver diseases, such as cholestasis and non-alcoholic fatty liver disease. Researchers also explore its anti-inflammatory and immunomodulatory properties, making it relevant in studies related to inflammatory bowel disease and other gastrointestinal disorders. Its applications extend to drug development, where it is used as a reference standard for analytical purposes.
