NADP(β-Nicotinamide adenine dinucleotide phosphate)

NADP is a coenzyme, which is formed by niacinamide adenine dinucleotide and phosphate molecule through an ester bond. It exists widely in the biological world and can be used for reduction reaction. It’s also a major component in various diagnosis kit, especially enzyme activity assays.

Technical principles

NADP is a coenzyme of dehydrogenase, and acts as a hydrogen acceptor in the reaction process. It accepts hydrogen through chemical osmotic coupling in the electron transport chain and reduces itself to NADPH.

Advantages

1) Good water solubility;

2) Good stability.
