what is the optimal ph of pepsin
7 For general digestion of proteins, suggestedconditions are a 0.4% solution of pepsin in10 mM HCl, and digestion for 30-90 minutes at 37 Â°C.Pepsin has optimal activity with native proteins atapproximately pH 1.0, but with some denaturedproteins the optimal activity is at approximatelypH 1.5-3.5.
