title: Electrochemical regeneration of nicotinamide adenine dinucleotide.
abstract: Reduced nicotinamide adenine dinucleotide (NADH) has been characterized electrochemically by solid electrode voltammetry and controlled potential electrolysis. Photometric and enzymatic assay showed that enzymatically active nicotinamide adenine dinucleotide (NAD-+) could be regenerated electrolytically from its reduced form without the use of so-called electron mediators. Complete regeneration of enzymatically active NAD can be expected in pyrophosphate buffers and phosphate buffers during the electrolysis. Advantages of electrochemical regeneration of coenzymes are discussed, especially with regard to immobilization of enzymes.
