Description

Application

β-NADPH is suitable for use in:

• desaturation of fatty acids
• an assay of desaturase activity
• the histochemical detection of NADPH diaphorase activity in rat, rabbit and pheasant thoracic spinal cord
• the measurement of glutathione in oligodendrocyte cultures

Biochem/physiol Actions

β-NADPH is the reduced form of NADP⁺ generated by the pentose phosphate pathway. It serves as a carrier of reducing power and transfers H⁺ and 2 e^– to the oxidized precursors in the reduction reactions of biosynthesis. It is an essential coenzyme for the catalytic activity of enzymes such as glutathione reductase, diacetyl reductase, dihydrofolate reductase, glutamic dehydrogenase, p-hydroxybenzoate hydroxylase, NADPH-FMN oxidoreductase, nitrate reductase, and thioredoxin reductase. It is also a part of cytochrome P₄₅₀ electron transport systems.

NADPH is an electron donor and a cofactor for many redox enzymes including nitric oxide synthetase.
