Sodium taurochenodeoxycholate is widely used in biochemical research as a bile salt surfactant. It plays a critical role in solubilizing membrane proteins and lipids, making it essential for studying cellular structures and functions. In drug delivery systems, it enhances the absorption of poorly soluble drugs by improving their solubility and permeability. Additionally, it is utilized in cell culture applications to maintain cell membrane integrity and facilitate nutrient uptake. Its ability to mimic natural bile salts also makes it valuable in studying digestive processes and liver function.
