What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a dinucleotide coenzyme and the oxidised form of the NAD+/NADH redox pair. In the laboratory it is used as a cofactor or substrate in enzyme assays, including those involving sirtuins, PARPs and CD38.
Is NAD+ a peptide?
No. NAD+ is a dinucleotide, not a chain of amino acids, so it has no amino acid sequence. Suppliers often list it alongside research peptides. Its identity is confirmed by mass spectrometry and HPLC rather than by sequencing.
What are the specifications of NAD+ 500mg?
NAD+ 500mg is nicotinamide adenine dinucleotide (CAS 53-84-9, C21H27N7O14P2, 663.43 g/mol), supplied as 500mg per unit.
