Gastric lipase hydrolyzes the ester bonds of triglycerides in the stomach. Fatty acids and diacylglycerols are produced from this reaction. The long chain free fatty acids have the ability to prevent gastric lipase from hydrolyzing more triglycerides. In this case, gastric acid will be responsible for less than 30% of lipid hydrolysis. These enzymes are found in the cytoplasm and cell membranes of gastric cells. Gastric lipase is not the primary lipase needed for the majority of triglyceride hydrolysis. Outside of the stomach, gastric lipase can hydrolyze triacylglycerol in the duodenum with the help of other lipases and bile secretion. It is an essential enzyme for hydrolyzing milk fat globule membranes. For a newborn with an underdeveloped pancreas, LIPF plays a more important role in lipid digestion compared to an adult with a fully functioning pancreas. There is typically an increase in production of LIPF when the pancreas is unable to operate at its optimal potential. Low levels of LIPF are typically seen in the tumors of gastric cancer patients.
