Detailed explanation-1: -Lipase is an enzyme the body uses to break down fats in food so they can be absorbed in the intestines. Lipase is produced in the pancreas, mouth, and stomach.
Detailed explanation-2: -While all lipases hydrolyze triglycerides and/or phospholipids, each has specific functions in vivo, including absorption of dietary fats (PL), remodeling and uptake of lipoproteins (LPL, HL and EL) and regulation of fatty acid influx in adipose tissue, muscle and the heart.
Detailed explanation-3: -Classically, lipases catalyse the hydrolysis of triglycerides: triglyceride + H2O → fatty acid + diacylglycerol. diacylglycerol + H2O → fatty acid + monacylglycerol. monacylglycerol + H2O → fatty acid + glycerol.
Detailed explanation-4: -Lipases hydrolyze triglycerides (fats) into their component fatty acid and glycerol molecules. Initial lipase digestion occurs in the lumen (interior) of the small intestine.
Detailed explanation-5: -Pancreatic lipase exhibits optimal activity under alkaline conditions and hydrolyzes triglycerides to fatty acids and glycerol, but mono-and diglycerides are also end products.
