NAD + is also consumed by different NAD+-consuming enzymes, such as CD38, CD157, PARPs and the NAD-dependent deacetylases (sirtuins,such as Sir2. [76]). [77] These enzymes act by transferring an acetyl group from their substrate protein to the ADP-ribose moiety of NAD +; this cleaves the coenzyme and releases nicotinamide and O-acetyl-ADP-ribose.
“NAD+ (the oxidized version of NAD) is a crucial coenzyme involved in hundreds of metabolic reactions, particularly those related to energy production, DNA repair, and cell signaling.
NAD is commonly called by other names, including NAD+ or NADH. These are both forms of NAD — NAD+ is the positively charged form, which has lost an electron, and NADH is the neutral form which ...
Nicotinamide adenine dinucleotide phosphate, abbreviated NADP [1] [2] or, in older notation, TPN (triphosphopyridine nucleotide), is a cofactor used in anabolic reactions, such as the Calvin cycle and lipid and nucleic acid syntheses, which require NADPH as a reducing agent ('hydrogen source').

Oxidoreductases, enzymes that catalyze oxidation-reduction reactions, constitute Class EC 1 of the IUBMB classification of enzyme-catalyzed reactions. [2] Any of these may be called dehydrogenases, especially those in which NAD + is the electron acceptor (oxidant), but reductase is also used when the physiological emphasis on reduction of the substrate, and oxidase is used only when O 2 is the ...
