The molecule is the oxidised form of nicotinamide adenine dinucleotide found in all living cells. In metabolism, NAD(+) is involved in redox reactions, carrying electrons from one reaction to another. It has a role as an Escherichia coli metabolite, a mouse metabolite and a cofactor. It is a NAD(P)(+) and a NAD. It derives from a deamido-NAD(+). It is a conjugate acid of a NAD zwitterion and a NAD(1-).
