Description_x000D_ General description_x000D_ Nicotinic acid adenine dinucleotide (deamido-NAD, NAAD) is a closely related analog of NAD+. It is used to study the structure of nicotinate mononucleotide adenylyltransferase(s) (NMN/NaMN). NAAD is used as a substrate to study the specificity and kinetics of nicotinamide adenine dinucleotide synthetase(s) (NADS). In addition, it is also used as a co-substrate to study mechanisms of members of the Sir2 class of NAD+-dependent deacetylase._x000D_ Application_x000D_ Nicotinic acid adenine dinucleotide sodium salt has been used as an internal standard during high performance liquid chromatography (HPLC) metabolite measurement. It has also been used as a substrate in nicotinamide adenine dinucleotide (NAD) biosynthesis._x000D_ Packaging_x000D_ 25, 100 mg in poly bottle_x000D_ Other Notes_x000D_ Analog of β-NAD
