Polarographic catalytic wave of hydrogen—Parallel catalytic hydrogen wave of bovine serum albumin in the presence of oxidants

A polarographic catalytic hydrogen wave of bovine serum albumin (BSA) at about-1.80 V (vs. SCE) in NH4Cl-NH3 · H2O buffer is further catalyzed by such oxidants as iodate, persulfate and hydrogen peroxide, producing a kinetic wave. Studies show that the kinetic wave is a parallel catalytic wave of hydrogen, which resulted from that hydrogen ion is electrochemically reduced and chemically regenerated through oxidation of its reduction product, atomic hydrogen, by oxidants mentioned above. It is a new type of poralographic catalytic wave of protein, which is suggested to be named as a parallel catalytic hydrogen wave.
