Nicotinamide Adenine Dinucleotide se yon coeznyme ki fòme ak yon baz Adenine ak yon baz nikotinamid ki konekte pa yon pè nan gwoup bridging fosfat. β-Nicotinamide Adenine Dinucleotide aji kòm yon coenzyme nan reyaksyon redox, tankou yon donatè nan ADP-riboz mouvman nan reyaksyon ADP-ribosilasyon ak tou kòm yon précurseur nan dezyèm mekanis nan sikilik ADP-riboz. β-Nicotinamide Adenine Dinucleotide tou aji kòm yon substra pou ligaz bakteri ADN ak yon gwoup nan anzim ki rele sirtuins ki itilize NAD + yo retire gwoup asetil nan pwoteyin.

Nicotinamide Adenine Dinucleotide is a coeznyme consisting of an adenine base and a nicotinamide base connected by a pair of bridging phosphate group. β-Nicotinamide Adenine Dinucleotide acts as a coenzyme in redox reactions, as a donor of ADP-ribose moieties in ADP-ribosylation reactions and also as a precursor of the second messenger molecule cyclic ADP-ribose. β-Nicotinamide Adenine Dinucleotide also acts as a substrate for bacterial DNA ligases and a group of enzymes called sirtuins that use NAD+ to remove acetyl groups from proteins.
