| NADPH dehydrogenase (quinone) | A flavoprotein similar to NADH dehydrogenase (quinone), but oxidizing NADPH. Synonym: DT-diaphorase, menadione reductase, phylloquinone reductase, quinone reductase. (05 Mar 2000) |
|---|---|
| NADPH diaphorase | <enzyme> A flavoprotein that reversibly oxidises NADPH to NADP and a reduced acceptor. Chemical name: NADPH:(acceptor) oxidoreductase Registry number: EC 1.6.99.1 (12 Dec 1998) |
| NADPH oxidase | <enzyme> A plasma membrane-associated enzyme complex that catalyses the univalent reduction of oxygen using NADPH as an electron donor. The superoxide anion formed acts as an oxidant in the phagocyte microbicidal system, proceeding through a series of electron transfer reactions that form the respiratory burst. Various genetic defects in the system result in chronic granulomatous disease (granulomatous disease, chronic). Registry number: EC 1.6.- (12 Dec 1998) |
| NADPH-cytochrome c2 reductase | <enzyme> An enzyme catalyzing the reduction of 2 ferricytochrome c2 to 2 ferrocytochrome c2 at the expense of NADPH. Synonym: cytochrome c2 reductase. (05 Mar 2000) |
| NADPH-ferrihemoprotein reductase | <enzyme> A flavoprotein that catalyses the reduction of haem-thiolate-dependent monooxygenases and is part of the microsomal hydroxylating system. Its physiological acceptor is probably cytochrome p-450. Chemical name: NADPH:ferrihemoprotein oxidoreductase Registry number: EC 1.6.2.4 (12 Dec 1998) |
| NADPH-tetrazolium reductase | <enzyme> Reported to possess activity identical with NADPH cytochrome c reductase EC 1.6.2.4 Registry number: EC 1.6.2.- Synonym: NADPH-neotetrazolium reductase, NADPH-nbt reductase (26 Jun 1999) |
| nadroparin | <chemical> A heparin fraction with a mean molecular weight of 4500 daltons. It is isolated from porcine mucosal heparin and used as an antithrombotic agent. Pharmacological action: anticoagulant, fibrinolytic agent. (12 Dec 1998) |
| NAD |
An important coenzyme, functioning as a hydrogen carrier in a wide range of redox reactions; the H is carried on the nicotinamide residue. The oxidized form of the coenzyme is written NAD+, the reduced form as NADH (or NADH+H+).

| NADP+ |
An important coenzyme, functioning as a hydrogen carrier in a wide range of redox reactions; the H is carried on the nicotinamide residue. The oxidized form of the coenzyme is written NADP+, the reduced form as NADPH. Many oxidoreductases are specific for either NAD or NADP, although some can function with either. As a broad generalization, NADP is more commonly associated with biosynthetic reactions, NAD with catabolic and energy-yielding reactions.
