Pepsin is an enzyme that is released by the chief cells in the stomach and that degrades food proteins into peptides. Pepsin was discovered in 1836 by Theodor Schwann who also coined this enzyme's na...

In a further 10 healthy volunteers the levels of total pepsin activity and pepsinogen I were studied over 5 days by short-term oral intake of ranitidine. The total pepsin activity and pepsinogen I increased significantly in the sera after maximum-dose pentagastrin, but not after sham feeding.

2. Equilibrium studies on the unfolding of prochymosin and pepsinogen by urea were carried out at pH 7.5 and pH 9. . The results indicate ... These values agree with the free energy changes estimated from differential scanning calorimetry for the transition between the second intermediate and the final denatured state.

The paper discusses changes occurring in the enzymatic activity of pepsin in rat's gastric mucosa at early stages of carcinogenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine treatment with drinking water. All doses (5, 15, 45, 75 and 150 mg/l) proved to be effective and inhibited pepsinogen biosynthesis considerably.

Second, spectral changes which occur upon acidification of a pepsinogen solution and are reversed by neutralization are shown to be consistent with the chemical cleavage of pepsinogen during acidification.
