[13] [14] Pepsin is inactive at pH 6.5 and above, however pepsin is not fully denatured or irreversibly inactivated until pH 8.0. [11] [15] Therefore, pepsin in solutions of up to pH 8.0 can be reactivated upon re-acidification. jopベテランテニス

"WebPepsin is an enzyme belonging to the family of aspartic protease enzymes. All members of this class of enzymes have two aspartic acid residues within their structure that act as the active site. For the most part, this class of enzymes is active at acid pH. In the case of pepsin, the pH of optimal activity is extremely acid, between 1 and 4.
