NAD+

Unlike most items in this catalog, NAD+ isn't a peptide at all — it's a small dinucleotide molecule (two linked nucleotides) that occurs naturally in every living cell as a coenzyme, meaning it works alongside enzymes to shuttle electrons during metabolic reactions. The version sold here is a synthesized, lyophilized reference form of the same molecule, supplied for researchers who need a defined, traceable source of it rather than extracting it from biological material. Its research relevance centers on its role as an electron carrier in oxidation-reduction chemistry, which makes it a common reference compound in studies of cellular energy metabolism and mitochondrial function.
