Frequently asked questions about NAD+ as a research compound. Laboratory context only.
What is NAD+?
Nicotinamide adenine dinucleotide, a coenzyme with both redox and signaling roles in the cell — see also NAD+ in cellular research.
Is it a peptide?
No — it is a dinucleotide coenzyme, not a peptide, which is why its history runs parallel to, rather than within, the peptide field.
How is it supplied and stored?
As a lyophilized powder kept cold and dark; it is moisture-sensitive, so follow NAD+ reconstitution and storage and general storage guidance.
How is purity documented?
By HPLC and a certificate of analysis.
