Micelles: How They Aid Long-Chain Fat Absorption

The structure that assists in the absorption of long-chain fats is called the micelle. Micelles are tiny, spherical structures that are formed when bile salts, which are produced by the liver and stored in the gallbladder, interact with long-chain fats in the small intestine. The bile salts encircle the fat molecules, forming a protective layer that allows the fats to be absorbed by the intestinal cells.
