NADH's role in cellular respiration takes place with the electron transport chain. NADH is the junction of nicotinamide adenine dinucleotide (NAD+) and hydrogen. Thus, it is the reduced form of
Found in all living cells, NAD is called a dinucleotide because it consists of two nucleotidesjoined through their phosphategroups. One nucleotide contains an adeninenucleobaseand the other, nicotinamide. NAD exists in two forms: an oxidized and reducedform, abbreviated as NAD+and NADH(H for hydrogen), respectively.
NADH stands for nicotinamide adenine dinucleotide (NAD) + hydrogen (H). NAD+ is the form without hydrogen. NAD and NADH are essential for cellular respiration. These two cofactors help enzymes produce ATP (adenine triphosphate). ATP is commonly referred to as the energy currency in your body. This is because it powers every process in every cell.
Nicotinamide adenine dinucleotide (NAD) and its relative nicotinamide adenine dinucleotide phosphate (NADP) are two of the most important coenzymes in the cell. NADP is simply NAD with a third phosphate group attached as shown at the bottom of the figure.
Nicotinamide adenine dinucleotide (NAD+) is an essential coenzyme involved in several redox reactions. NAD + also serves as an important substrate for several enzymes associated with DNA repair, secondary messenger signaling, and transcriptional regulation.
