nicotinamide

 [nik″o-tin´ah-mīd]
nicotinamide-adenine dinucleotide (NAD) a coenzyme that is involved in many biochemical oxidation-reduction reactions. The symbols for the oxidized and reduced forms are NAD and NADH.
nicotinamide-adenine dinucleotide phosphate (NADP) a coenzyme similar to nicotinamide-adenine dinucleotide but involved in fewer reactions. The symbols for the oxidized and reduced forms are NADP and NADPH.

nic·o·tin·a·mide

(nik'ō-tin'ă-mīd),
The biologically active amide of nicotinic acid, used in the prevention and treatment of pellagra.

nicotinamide

/nic·o·tin·a·mide/ (nik″o-tin´ah-mīd) niacinamide.
nicotinamide adenine dinucleotide  (NAD) a coenzyme composed of nicotinamide mononucleotide in pyrophosphate linkage with adenosine monophosphate; it is involved in numerous enzymatic reactions, in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH).
nicotinamide adenine dinucleotide phosphate  (NADP) a coenzyme composed of nicotinamide mononucleotide coupled by pyrophosphate linkage to adenosine 2′,5′-bisphosphate; it serves as an electron carrier in numerous reactions, being alternately oxidized (NADP+) and reduced (NADPH).
