NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to cellular energy production. It is worth noting that NAD+ is technically a coenzyme, not a peptide, though it is commonly grouped with research compounds. It is studied in metabolic and aging research and supplied for research use only.
What NAD+ is
NAD+ is a coenzyme found in every living cell, where it plays a central role in the reactions that produce cellular energy. Unlike the peptides in this library, it is not a chain of amino acids; it is a different class of molecule, which is why it is described accurately as a coenzyme.

How it is studied
In the laboratory, NAD+ is studied in metabolic and aging research related to cellular energy. As a research compound, it is a study tool and is not approved or intended for human use.
