Recent research has uncovered a new basis for understanding bile salt extrusion, a process that is essential for the absorption of small molecules from the intestine. Bile salt extrusion is the process by which bile salts, molecules that are produced in the liver and secreted into the intestine, are removed from the intestine and excreted. This process is important for the absorption of small molecules, such as vitamins and minerals, from the intestine into the bloodstream. Scientists have recently uncovered the mechanism by which bile salt extrusion is regulated, providing new insight into how this process works.
