WebMechanisms of Absorption. Digestion breaks down food into smaller, soluble molecules. The products of digestion are absorbed through the intestinal lining. The absorption of amino acids and monosaccharides uses a similar mechanism - co-transport. The absorption of lipids takes place in a different way. WebChylomicrons are formed within intestinal cells to transport digested fats and other lipids through the lymph system. Which of the following statements is correct about the process of fat digestion? Bile salts act to emulsify lipids in the small intestine, which helps pancreatic lipase access fats for further digestion.
