Lipases perform essential roles in the digestion, transport, and processing of dietary lipids in most, if not all, living organisms. Lipase is an enzyme that catalyzes the hydrolysis of fats. Lipases are a subclass of the Esterases.
Lipase is an enzyme that breaks down dietary fats into smaller molecules called fatty acids and glycerol. A small amount of lipase, called gastric lipase, is made by cells in your stomach. This enzyme specifically digests butterfat in your food.
Abnormally high levels of the enzyme in your blood can be a sign of a health problem. The serum lipase test is used to measure the amount of lipase in the body. The lipase test is often ordered at the same time as the amylase test. An amylase test is used to diagnose diseases of the pancreas.
A lipase test measures the amount of this enzyme in a blood sample. High amounts of lipase may be found in the blood when the pancreas is damaged or when the tube leading from the pancreas (pancreatic duct) to the beginning of the small intestine is blocked
