NAD (β Nicotinamide Adenine Dinucleotide, Oxidized form) is an essential coenzyme utilized in biochemical research to investigate cellular metabolism, enzymatic reactions, and redox processes. This product is provided in a 5g quantity in its oxidized free acid form, suitable for experiments where NAD is required in its natural state. NAD is pivotal in energy metabolism, acting as a carrier of electrons in the processes of glycolysis, oxidative phosphorylation, and the citric acid cycle. It is also involved in DNA repair and cell signaling, making it indispensable in studies related to cellular function, aging, and disease mechanisms. NAD is a critical component for understanding energy transfer and metabolism at the cellular level.
