Following the pH-dependent experiments the scan-rate-dependent experiments were also conducted.
In addition to the peak shift with pH the electrochemical oxidation of 4-HMBA is greatly enhanced on an Au electrode in both scans with a more basic electrolyte Fig. Studies of proteins adapted to low pH have revealed a few general mechanisms by which proteins can achieve acid stability.
