6-Vinyl coenzyme Q0: Electropolymerization and electrocatalysis of NADH oxidation exploiting poly-p-quinone-modified electrode surfaces

6-Vinyl coenzyme Q0 serves as a convenient starting material for the formation of electropolymerized coenzyme Q0 on glassy carbon electrodes and the modified electrodes displays electrocatalytic activity toward NADH (β-nicotinamide adenine dinucleotide) oxidation. The detection of NADH was measured by differential pulse voltammetry, which reveals that the peak current is linear to the concentration of NADH within the range of 10–100 μM. This would be helpful for the understanding of the interaction between coenzyme Q0 and NADH in the biological process.
