Bile salt from pig is widely used in biochemical research and pharmaceutical applications. It plays a crucial role in the digestion and absorption of fats and fat-soluble vitamins, making it valuable in studies related to lipid metabolism. In the pharmaceutical industry, it is utilized as an excipient in drug formulations to enhance the solubility and bioavailability of poorly water-soluble drugs. Additionally, it is employed in cell culture techniques to isolate and study membrane proteins. Its emulsifying properties also make it useful in the preparation of various diagnostic reagents and in the production of dietary supplements aimed at improving digestive health.
