In this paper, differential pulse voltammetry (DPV) was applied to study the effects of aluminum Al(Ⅲ) on the lactate dehydrogenase (LDH) activity. Michaelis-Menten constant (Km^NADH) and maximum velocity (vmax) in the enzyme promoting catalytic reaction of "pyruvate(Pyr) + NADH + H^+ ↑LDH←→lactate + NAD^+" under different conditions by monitoring DPV reduction current of NAD^+ were reported.
