Lipase mainly plays a role in helping the body to digest fat, and has the effect of breaking down fat and catalyzing. Lipase is a kind of enzyme substance in the digestive fluid of human body, which can break down the fat in the stomach into glycerol and fatty acid, so it has the effect of helping the body to digest fat. Lipase, also called glycerol ester hydrolase, belongs to the class of carboxylester hydrolases, which can also gradually hydrolyze triglycerides into glycerol and fatty acids and play a role in breaking down fats. Lipase also belongs to a kind of enzyme with strong catalytic ability and has many catalytic functions, which can help catalyze triacylglycerol esters, and also catalyze the hydrolysis and alcoholysis of some insoluble esters. The pancreas is the most important source of lipase in the body. Increased serum lipase is commonly seen in acute pancreatitis and pancreatic cancer, and occasionally in chronic pancreatitis. It is recommended to seek medical advice when abnormalities occur.
