Pancreatic juice

Overview
Pancreatic juice is a juice produced by the pancreas. It contains a variety of enzymes. They include 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 hormone secretin, which is released by the duodenum upon detection of proteins and fats. Pancreatic secretion consists of an aqueous bicarbonate component from the duct cells and enzymatic component from the acinar cells.
