The degradation products empty from the stomach into the small intestine. Since the products of pepsin are only partially cleaved, they are polypeptides. These molecules are too large to be absorbed by the intestinal cells. They are further degraded by chymotrypsin, trypsin, and specific enzymes th...

Pepsin, the first animal enzyme discovered (Florkin, 1957), is an acidic protease that catalyzes the breakdown of proteins into peptides in the stomach, while it does not digest the body's own proteins. What is chronic atrophic gastritis? Listen. Autoimmune atrophic gastritis is a chronic infl...
Pepsin is a proteolytic enzyme released as a proenzyme pepsinogen by the main cells of the gastric glands. GastricHClacts as an activator. Pepsin's optimum pH is1.8, which is quite acidic.Because the carboxylic acid group on the amino acid in the enzyme's active site must be in its ...
