| '''Steapsin''' belongs to the class of digestive enzymes called ] found in the pancreatic juice that catalyzes the hydrolysis of triglycerides (main constituent in vegetable oils and animal fat) to fatty acids and glycerol. When food travels through the oral cavity and down the esophagus into the stomach, ] such as ] are released where it cleaves large proteins into smaller ] fragments so further digestion and absorption can occur in the duodenum, the first part of the small intestine. Fats are minimally digested in the stomach by gastric lipases but most digestion occurs in the small intestine. ] | |||
| == Function == | |||
| The lipase steapsin is secreted from the pancreas to break down triglycerides to liberate the fatty acids and glycerol. The free fatty acids can then be absorbed to the liver and kidneys where it may be converted to ], a constituent in the process of ] to ultimately generate energy in the form of ATP via the citric acid cycle. Fatty acids that are not used for energy can then be allowed to cross the intestinal barrier to be repackaged into fatty tissue. | |||

| ], a ], functions as a steapsin inhibitor. Trypsin is produced in the pancreas and secreted as ], an inactive precursor of trypsin. The reason for this is to prevent trypsin from acting upon the pancreas. Upon entering the ], ] is secreted which activates trypsin. Trypsin reduces steapsin activity in the gastric tract by digesting it (]). | |||
| == Anti-inhibitors == | |||
| === Egg Albumen === | |||
| ] or egg whites acts as a ] inhibitor because egg whites are full of protein which allows trypsin to act upon the egg whites instead of steapsin. This allows the trypsin to be neutralized and allows steapsin's activity to remain unchanged. | |||
