Ph optimum for pepsin
WebApr 10, 2024 · In acidic environments with a pH of 1.5 to 2.5, pepsin is most active. Pepsin works best at temperatures between 37 and 42 degrees Celsius. As a result, the stomach is the main site of synthesis and function (pH 1.5 to 2). In humans, pepsin concentrations in the stomach range from 0.5 to 1 mg/mL.

The effects of salt concentration and pH on the digestion products were investigated by size exclusion chromatography under various conditions, which revealed a pH-dependent aggregation of some of the low molecular weight Fc and non-IgG fragments.
WebThe optimal pH for peptic activity is generally between 1.6 and 2.5, but the effect of pH may vary with the substrate. Pepsin is capable of hydrolyzing peptide bonds of most proteins, mucin being one important exception. Pepsin splits bonds involving phenylalanine, tyrosine, and leucine most readily but can hydrolyze almost all other peptide bonds. WebOptimum pH value of pepsin is: a) 1.4 b) 2 c) 3.5 d) 5.
