Detailed explanation-1: -Examples of nutrients absorbed by the small intestine include carbohydrates, lipids, proteins, iron, vitamins, and water.
Detailed explanation-2: -Intestinal uptake of lipids. The mixed micelles in the small intestinal lumen promote the absorption of fatty acids and cholesterol by facilitating transport of these lipids across the unstirred water layer adjacent to the surface of the apical membrane of enterocytes.
Detailed explanation-3: -These fatty acids (and other lipids such as cholesterol) are packaged into micelles, which are taken up by the cells of the small intestine (called enterocytes).
Detailed explanation-4: -Pancreatic enzymes called lipases then hydrolyze the dispersed fats to give monoglycerides and free fatty acids. These products are absorbed into the cells lining the small intestine, where they are resynthesized into triglycerides.
