Pancreatic juice is a liquid secreted by the pancreas, which contains a variety of enzymes, including trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase, nucleases 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, vitamins. Pancreatic secretion consists of an aqueous bicarbonate component from the duct cells and enzymatic component from the acinar cells.
Famous quotes containing the word juice:
“It is not all bad, this getting old, ripening. After the fruit has got its growth it should juice up and mellow. God forbid I should live long enough to ferment and rot and fall to the ground in a squash.”
—Emily Carr (1871–1945)
