NAD+

Nicotinamide adenine dinucleotide, or NAD+, is a central cellular coenzyme involved in oxidation-reduction reactions. It is used in laboratory studies involving cellular energy metabolism, mitochondrial activity, DNA-repair-associated enzymes, chromatin regulation, and stress-response pathways.

NAD+ is a biochemical cofactor rather than a peptide. This material is intended exclusively for analytical and laboratory research and is not intended for human or veterinary use.
