Did you know?
WebPepsin is an enzyme that is produced in the stomach and plays a crucial role in the digestion of proteins. It is activated when it comes into contact with hydrochloric acid, which is produced by the cells lining the stomach. When we eat food, it is mixed with saliva and other digestive juices in the mouth, forming a bolus. WebPepsinogen is a precursor of pepsin stored in the stomach walls. It is converted into pepsin by hydrochloric acid. It is the activated in the form of pepsinogen. Pepsinogen --- …
WebActivation of Pepsinogen for Quantitative Analysis of NH,- terminal 8 Residues-Activation mixtures were prepared in order to quantify the chemical cleavage of pepsinogen which occurs when pepsin is formed under various experimental conditions. Pepsinogen, 20 to 25 mg, was dissolved in 2 mM Tris-chloride, pH WebPepsin activity in specimens from the gastric body ranged from 180 to 780 pepsin units/mg protein (using hemoglobin as substrate). The antrum had significantly lower pepsin activity (P less than 0.001) than the gastric body. As with lipase activity, there were no statistically significant differences in pepsin activity among age groups.
WebPepsinogen I is synthesized and secreted by chief cells of the oxyntic glandular region of the stomach, and pepsinogen II is synthesized and secreted by the pyloric region of the stomach.
