(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).
