By purchasing, the buyer confirms use strictly for scientific research purposes and not for human or animal consumption.
Product Overview
NAD+ (nicotinamide adenine dinucleotide) is an endogenous nucleotide-derived coenzyme central to cellular redox chemistry, energy metabolism, mitochondrial function, and enzyme-mediated signaling.
NAD+ participates in reversible oxidation-reduction reactions through conversion between its oxidized NAD+ and reduced NADH forms. It also serves as a substrate for NAD+-consuming enzymes including sirtuins, poly(ADP-ribose) polymerases (PARPs), and CD38-associated pathways.
Unlike many products in the OPTMZ Peptides catalog, NAD+ is not a peptide. It is more accurately classified as a cellular redox coenzyme and nucleotide-derived metabolite.
The lot-specific purity, measured content, identity, and CAS number come directly from the Krause Analytical COA.
Each tested batch of NAD+ undergoes analytical evaluation to verify chromatographic purity, identity, compound content, and analytical consistency.
For the submitted OPTMZ sample, Krause Analytical reported:
The laboratory states that the data presented are from the analyzed sample and meet its internal quality-assurance criteria unless otherwise flagged.
Endotoxin Status: Not reported on this COA. This lot should therefore not be described as endotoxin-tested or endotoxin-passing based on the supplied document.
NAD+ should be handled by qualified professionals in controlled laboratory environments. Appropriate storage conditions should be maintained to preserve chemical stability and analytical integrity.
Avoid unnecessary exposure to heat, moisture, light, and repeated temperature fluctuations. Experimental preparation, storage, and handling should follow validated laboratory procedures appropriate to the intended research application.
NAD+ is investigated extensively across biochemistry, cell biology, mitochondrial biology, and metabolic research.
Research areas include:
NAD+ functions as an electron-accepting coenzyme in numerous dehydrogenase reactions and is converted to NADH during cellular metabolism. Beyond redox chemistry, NAD+ is consumed by several major enzyme families involved in signaling and cellular regulation.
These research contexts describe established biochemical functions of NAD+ and do not establish therapeutic efficacy of the OPTMZ research material.
NAD+ is relevant to controlled experimental investigations involving cellular energy metabolism, mitochondrial function, redox balance, NAD+-dependent enzyme activity, DNA-associated signaling, cellular stress responses, and metabolic regulation.
Because NAD+ serves both as a redox cofactor and a substrate for regulatory enzymes, it is particularly useful for studying the relationship between cellular energy state and intracellular signaling.

Cellular Redox Coenzyme / NAD Metabolism Research Compound
Biochemistry; Mitochondrial Biology; Metabolic Biology; Cellular Redox Biology; Molecular Biology; Enzymology
Multiple NAD+-dependent enzymes and metabolic pathways Key experimentally relevant systems include: Oxidoreductases / dehydrogenases Sirtuins (SIRT family) Poly(ADP-ribose) polymerases (PARPs) CD38-associated NADase activity NAD+ is therefore better characterized as a cofactor and enzyme substrate than as a single-target receptor ligand.
Established Biology / Clinical Research The biochemical roles of NAD+ in redox metabolism and enzyme signaling are firmly established, and NAD+ metabolism has also been extensively investigated in human physiology and clinical research. This classification refers to the scientific evidence surrounding the molecule, not the regulatory status or intended use of the OPTMZ research product.
NAD+ is a dinucleotide coenzyme composed of two ribonucleotide units connected through a pyrophosphate bridge. One nucleotide contains an adenine base, while the second contains a nicotinamide moiety that participates directly in reversible electron-transfer reactions. The oxidized form, NAD+, accepts a hydride equivalent during redox reactions to form NADH.
N/A — NAD+ is not a peptide. It is a nucleotide-derived dinucleotide coenzyme and therefore has no amino-acid sequence.
