The interaction with bile in the small intestine greatly increases the surface area over which lipases can come into contact with the triglycerides and hydrolyze them into amphipathic free fatty acids and monoglycerides, both of which can be absorbed by the intestinal epithelium.

Biohazard sharps containers. Chemicals in the chyme induce cells in the small intestine to secrete the hormones secretin, which stimulates water and bicarbonate secretion in the pancreas, and cholecystokinin (CCK), which stimulates enzyme secretion in the pancreas. 15. Chemical digestion: enzymatically breaking large molecules into However, when food is swallowed and transferred to the small intestine, chemical digestion of carbohydrates effectively stops. Gastric juice contains a number of substances, but the two most important for initiating protein digestion are hydrochloric acid (HCl) and the protease pepsin.
