Question: Is micelle same as chylomicrons?

Answer: During the process of fat digestion, the pancreatic lipase gets secreted into the lumen of the small intestine. With the help of bile salts, pancreatic lipase digest triglycerides to monoglycerides and fatty acids and gets packaged into small water-soluble molecules called micelles. Intestinal mucosal cells absorb digested fats that leave from these micelle molecules. Intestinal cells package these digestive products into lipoproteins called chylomicrons. After entering the intestinal mucosal cells, these end products of fat digestion combine with the proteins inside the Golgi apparatus and get repackaged into Chylomicrons. Chylomicrons that move out of the intestinal cells carry these end products of fat digestion into the lymph vessels and transport them into the lymph and thus enter the circulation to the body tissues.

Micelles consist of monoglycerides, free fatty acids along with bile salts. Chylomicrons consist of triglycerides, cholesterol, phospholipids, and protein.
