What is the role of the enzyme lipase?
Lipase is fat degrading enzyme.
Fat is water insoluble. Lipase is fat digesting enzyme .
Before digestion of fat it is to be made soluble in water. Because enzymes act only in aqueous medium.
For fat to dissolve in water bile salts of bile take a part. The action of bile salt on fat is also known as emulsification.
When bile salts temporarily make fat soluble, lipase acts on fat.
Chemically fat is made of fatty acids and glycerol.
Lipase acts on triglycerides to break it down to free fatty acids.
