Pancreatic juice

Pancreatic juice

Pancreatic juice is a juice produced by the pancreas. It contains a variety of enzymes, including trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase, and amylase.

Pancreatic juice is alkaline in nature due to the high concentration of bicarbonate ions. This is useful in neutralizing the acidic gastric acid, allowing for effective enzymic action.

Pancreatic juice secretion is regulated by the hormones secretin and cholecystokinin, which is produced by the walls of the duodenum upon detection of acid food, proteins and fats.Pancreatic secretion consists of an aqueous bicarbonate component from the duct cells and enzymatic component from the acinar cells.
