NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It is one of the most studied molecules in cell biology and metabolism research.
What is NAD+?
NAD+ is a dinucleotide: two nucleotides joined through their phosphate groups, one carrying adenine and the other nicotinamide. It was first identified by Arthur Harden and William John Young in 1906. In cells it cycles between an oxidized form (NAD+) and a reduced form (NADH).
