what is the type of cell in the stomach that releases pepsinogen and chymosin?
parietal cells
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 acid produced by gastric parietal cells. this type of cell also secretes gastric lipase enzymes, which help digest triglycerides into free fatty acids and di- and mono-glycerides. there is also evidence that the gastric chief cell secretes leptin in response to the presence of food in the stomach. leptin has been found in the pepsinogen granules of chief cells.
chief cell
rennet is a mixture of enzymes used to coagulate milk into cheese. originally it was available only from the fourth stomach of calves, and was scarce and expensive, or was available from microbial sources, which often produced unpleasant tastes. genetic engineering made it possible to extract rennet-producing genes from animal stomachs and insert them into bacteria, fungi or yeasts to make them produce chymosin, the key enzyme. the modified microorganism is killed after fermentation. chymosin is isolated from the fermentation broth, so that the fermentation-produced chymosin (fpc) used by cheese producers has an amino acid sequence that is identical to bovine rennet. the majority of the applied chymosin is retained in the whey. trace quantities of chymosin may remain in cheese.
