NAD (β Nicotinamide Adenine Dinucleotide, Oxidized form) is a vital coenzyme used in a wide range of biochemical research applications. This product is available in its oxidized free acid form, with a concentration of 25g. NAD is essential in redox reactions, where it acts as an electron carrier during cellular processes such as glycolysis and oxidative phosphorylation. It also plays a key role in DNA repair, gene expression regulation, and cell metabolism. NAD is used in laboratory experiments studying cellular respiration, aging, and diseases associated with mitochondrial dysfunction. Its diverse applications make it a fundamental tool for researchers studying metabolic pathways and cellular energy regulation.
