diphosphopyridine nucleotide[dī‚fäs·fə′pir·ə‚dēn ′nü·klē·ə‚tīd] (biochemistry) C21H27O14N7P2 An organic coenzyme that functions in enzymatic systems concerned with oxidation-reduction reactions. Abbreviated DPN. Also known as codehydrogenase 1; coenzyme 1; nicotinamide adenine dinucleotide (NAD). diphosphopyridine nucleotide
nic·o·tin·a·mide ad·e·nine di·nu·cle·o·tide (NAD, NAD+, NADH), (nik'ō-tin'ă-mīd ad'ĕ-nīn dī-nū'klē-ō-tīd), Ribosylnicotinamide 5'-phosphate (NMN) and adenosine 5'-phosphate (AMP) linked by phosphoanhydride linkage between the two phosphoric groups; binds as a coenzyme to proteins, serves in respiratory metabolism (hydrogen acceptor and donor) through alternate oxidation and reduction (NAD+ ⇋ NADH).
