NAD+

Description

NAD+ is a dinucleotide coenzyme made up of nicotinamide mononucleotide joined to adenosine monophosphate. It is not a peptide; it is the central redox cofactor in the cell, cycling between its oxidised and reduced forms in hundreds of enzymatic reactions, and it is also the substrate consumed by sirtuins and PARP enzymes.
