Contains pancreatic enzymes: α-amylase, lipase, trypsin, chymotrypsin.
α-amylase cleaves polysaccharides into glucose molecules.
Lipase cleaves fatty acids from triacylglyceride molecules at positions 1 and 3. 2-monoglycerides and released fatty acids are absorbed in the upper part of the small intestine with the participation of bile acids. At a pH below 4, the lipolytic activity of pancreatic lipase irreversibly increases.
Under the influence of enterokinase of the small intestine of trypsinogen, trypsin, which, in turn, activates proteolytic enzymes and cleaves peptide bonds formed by lysine and arginine.
By the feedback mechanism, secretion of the pancreas is inhibited, which is manifested by an analgesic effect.
