NAD+

Description

For Research Use Only. This product is supplied exclusively for laboratory research and is not intended for human or veterinary use.

NAD+ Research Compound

Nicotinamide adenine dinucleotide (NAD+) is an oxidised dinucleotide coenzyme present in living cells. It is not a peptide. ZENTRA supplies NAD+ as high-purity lyophilised research material in 100mg and 500mg formats for controlled laboratory and analytical applications.

NAD+ participates in oxidation-reduction reactions by accepting electrons to form NADH. It also acts as a substrate for NAD-consuming enzymes including sirtuins, poly(ADP-ribose) polymerases and CD38-family enzymes.

Technical Specifications

Independent Batch Testing

Every current ZENTRA NAD+ batch is independently tested and records an HPLC purity result above 99%. The batch number on the product label can be checked against the corresponding third-party report in our Batch Verification and COA Centre. Researchers should consult the individual report for the exact analytical methods, result and testing date for their supplied batch.

NAD+ Research Context

Cellular research has established NAD+ as a central redox cofactor and enzyme substrate. Experimental studies in cells and animal models have investigated age-related changes in intracellular NAD pools, nuclear-mitochondrial communication and CD38-dependent NAD consumption.

Those studies examine cellular NAD metabolism and, in some cases, NAD-raising interventions or enzyme manipulation. They do not establish that externally supplied NAD+ research material produces a therapeutic outcome in humans. Route, cellular uptake, compartmentalisation and chemical form are separate research questions.

Storage and Handling

For long-term storage, keep unopened lyophilised material at approximately -20°C. For short-term laboratory storage, maintain at 2-8°C. Protect the vial from light, moisture and repeated temperature changes. Use appropriate laboratory handling procedures and consult your institutional protocol before preparing research solutions.

NAD+ Research FAQs

Is NAD+ a peptide?

No. NAD+ is a dinucleotide coenzyme. It belongs in the research catalogue because of its use in cellular-metabolism studies, but it should not be chemically described as a peptide.

What does the plus sign mean?

The plus sign denotes the oxidised form of the NAD redox pair. NAD+ can accept electrons and be reduced to NADH during biochemical reactions.

Which sizes are available?

This product is available as 100mg and 500mg of lyophilised research material. Stock availability is shown against each option.

Why can molecular mass vary between records?

The 663.4 g/mol figure is for the free-acid basis. Sodium salts, other counter-ions and hydration states can change the measured formula mass, so the batch documentation should be consulted.

How is purity verified?

Every current batch is independently HPLC tested above 99% purity with online batch-level COA verification.

Is this product intended for human or veterinary use?

No. It is supplied strictly for laboratory research and analytical purposes.
