NAD+ (Nicotinamide Adenine Dinucleotide)

NAD+ (Nicotinamide Adenine Dinucleotide) is a vital coenzyme found in all living cells, playing a central role in energy metabolism, DNA repair, and cellular signaling. It exists in two forms: NAD+ (oxidized) and NADH (reduced), cycling between them to facilitate redox reactions in mitochondrial respiration and ATP production.

NAD+ (oxidized form): Acts as an electron acceptor in catabolic reactions

NADH (reduced form): Serves as an electron donor for ATP synthesis
