The pancreatic juices are secreted by the pancreas. Pancreatic juice consists of the following inactive enzymes. These enzymes are activated by the intestinal mucosal secretions.
Amylases, lipases and nucleases are the enzymes found in pancreatic juice. Chymotrypsin, carboxypeptidase, procarboxypeptidases, and trypsinogen are some other enzymes found in pancreatic juice. All these enzymes play an important role in the digestion of food.
Role of enzymes found in pancreatic Juice
- Trypsinogen – An inactive form of trypsinogen is converted into an active form, trypsin by enterokinase. Trypsin is used to convert the protein molecules into dipeptides.
- Chymotrypsinogen – An inactive form of chymotrypsinogen is converted into an active form, chymotrypsin. Proteins are denatured into dipeptides by chymotrypsin.
- Procarboxypeptidases – An Inactive form of procarboxypeptidase is converted into an active form, carboxypeptidase. Carboxypeptidase is also used to denature the protein.
- Amylases – Amylases are used to denature the polysaccharides into the disaccharides.
- Lipases – Lipases are used to convert the fats into diglycerides and monoglycerides.
- Nucleases – Nucleases are used to convert the nucleic acids into nucleotides and nucleosides.
