(1) Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, continuing the process of digestion that began in the stomach. Trypsin is produced by the pancreas in an inactive form called trypsinogen.

(2) The gastric lipase is produced within the stomach and its primary function is to digest fatty acids. The pharyngeal lipase is secreted by the human salivary glands and attacks fatty acids from the moment the food is inside the mouth. The hepatic lipase is a digestive enzyme produced by the liver.

(3) succus entericus The alkaline secretion produced by glands in the wall of the duodenum, consisting of water, mucoproteins, and hydrogencarbonate ions. It helps to counteract the highly acidic and proteolytic chyme entering the small intestine from the stomach, and thus protects the duodenum from damage.
