Hydrophobic bile acids

As molecules with hydrophobic and hydrophilic regions, conjugated bile salts sit at the lipid/water interface and, above the right concentration, form micelles. The added solubility of conjugated bile salts aids in their function by preventing passive re-absorption in the small intestine. As a result, the concentration of bile acids/salts in the small intestine is high enough to form micelles and solubilize lipids.
