The 1973 discovery of lingual lipase, which is secreted by lingual serous glands and hydrolyzes medium-and long-chain triglycerides in the stomach, has renewed interest in the gastric phase of fat digestion.he 1973 discovery of lingual lipase, which is secreted by lingual serous glands and hydrolyzes medium-and long-chain triglycerides in the stomach, has renewed interest in the gastric phase of fat digestion.
Lingual lipase uses a catalytic triad consisting of aspartatic acid-203 (Asp), histidine-257 (His), and serine-144 (Ser), to initiate the hydrolysis of a triglyceride into a diacylglyceride and a free fatty acid.First, there is a series of deprotonations that make the serine a better nucleophile.n the uterus, the fetus is dependent on a high-carbohydrate diet, and lingual as well as gastric lipases are present in the fetus from 26 weeks of gestation on. After birth, fat in mother's milk or a milk substitute Furthermore, milk fat is not a good substrate for pancreatic lipase.
