Nicotinamide adenine dinucleotide phosphate, abbreviated NADP+, is a cofactor used in anabolic reactions, such as the Calvin cycle and lipid and nucleic acid syntheses, which require it as a reducing agent ('hydrogen source'). NADPH is the reduced form, whereas NADP+ is the oxidized form. The reduced form, NADPH is used by all forms of cellular life as an electron donor as part of many biosynthetic reactions.

NADP+ differs from NAD+ by the presence of an additional phosphate group on the 2' position of the ribose ring that carries the adenine moiety. This extra phosphate is added by NAD+ kinase and removed by NADP+ phosphatase. As cofactors for enzyme reactions in mammals, NAD+ and NADPH are typically the active forms (outside of oxidative phosphorylation). NAD+ participates in oxidative (and usually catabolic) reactions, while NADPH participates in reductive (and usually anabolic) reactions.
