A coenzyme, not a peptide
Although it appears alongside peptides in the catalog, this material is a coenzyme. Its oxidized and reduced forms, and the way an assay measures them, are central to understanding the research.
01
A different class of research compound
The reference structure is a dinucleotide rather than a chain of amino acid residues. The plus notation identifies the oxidized coenzyme convention. It should not be described with a peptide sequence simply because it is sold in a vial beside peptide products.
A 2001 Cell paper examined an NAD-dependent deacetylase in cellular experiments. It is one example of research extending beyond the coenzyme’s classical role in redox reactions to its involvement as a substrate in other enzyme systems.

02
Specify which form the assay measures
The oxidized and reduced forms are distinct chemical states. An assay reporting a total pool, a ratio or one state is answering a different question. Preserve that distinction when comparing source results or planning a material record.
A reference formula describes a particular chemical form. Salt composition and hydration can affect supplied-material mass, so compare the stated form rather than assuming every reported molecular weight uses the same basis.
03
From the reference record to the catalog
The vial listing and the premixed spray use separate product records. For the liquid, total volume and total labeled material are different measurements. Check which units are used in the report before comparing it with a vial amount.
Published enzyme research explains scientific context. It does not determine the identity, content or storage history of the bottle in your order. Those belong to the label, batch documentation and your laboratory records.
A little more clarity
Questions, answered
Is this a peptide?
No. It is a dinucleotide coenzyme. A peptide sequence would not describe its structure.
Is a total amount the same as concentration?
No. Concentration relates an amount to a volume. Read the bottle volume and the report units alongside the labeled amount.
