Zymogenic (chief) cells

Pepsin cells
|
Detailed explanation-1: -The gastric chief cell (also known as a zymogenic cell or peptic cell) is a cell in the stomach that releases pepsinogen and chymosin. Pepsinogen is activated into the digestive enzyme pepsin when it comes in contact with hydrochloric acid produced by gastric parietal cells.
Detailed explanation-2: -The chief cells secrete pepsinogen, a moderately sized zymogen protein with a molecular weight of 40, 400. Pepsin, an enzyme with a molecular weight of 32, 700, is formed in the acidic environment of the stomach when pepsinogen loses its activation peptides.
Detailed explanation-3: -A gastric chief cell (or peptic cell, or gastric zymogenic cell) is a type of gastric gland cell that releases pepsinogen and gastric lipase. It is the cell responsible for secretion of chymosin in ruminant animals.
