Explanation:
Detailed explanation-1: -Summary: Digestion of dietary fat starts in the stomach, where lingual lipase hydrolyzes triglycerides to free fatty acids and partial glycerides at pH 3.0-6.0. Lingual lipase is secreted continuously from lingual serous glands and accumulates in the stomach between meals, when gastric pH is <3.0.
Detailed explanation-2: -This enzyme has a low pH optimum and preferentially cleaves the fatty acyl ester bond at position 3, producing fatty acid and diglyceride. The bulk of lipase activity comes from the pancreas.
Detailed explanation-3: -Human gastric lipase is produced by chief cells and is colocated with pepsin. Cells that have the appearance of chief cells appear at 12 to 13 weeks’ gestation.
