فكر مي كنم اين پيج خوب توضيح داده است :
Introduction to NAD/NADH
NAD+ + 2H -> NADH + H+
Structures of NAD & NADH
اينم يك توضيح كوتاه :
NADH, short for nicotinamide adenine dinucleotide, is an important pyridine nucleotide that functions as an oxidative cofactor in eukaryotic cells. NADH plays a key role in the production of energy through redox reactions. NAD serves as a cofactor for dehydrogenases, reductases and hydroxylases, making it a major carrier of H+ and e- in major metabolic pathways such as glycolysis, the triacarboxylic acid cycle, fatty acid synthesis and sterold synthesis.
