[Electrochemical regulation of the dehydrogenase process]

On changing stepwise the polypyrrole (PP) electrode potential a reverse change in the equilibrium concentration of a reduced coenzyme is observed in 0.1 M KNO3 solution containing nicotinamide adenine dinucleotide (NAD+), ethyl alcohol, alcohol dehydrogenase and electrode system based on PP-modified platinum. Direct measurements of the solution pH and calculations verify the conclusion mode that the electrochemical control of dehydrogenase process proceeds via the pH change of the solution.
