Close
Step 1
Step 2: Recall the structures of NAD+ and NADH. NAD+ (nicotinamide adenine dinucleotide, oxidized form) has a positively charged nitrogen in its nicotinamide ring, which makes the ring aromatic. It has a delocalized pi-electron system (6 pi electrons in a cyclic, Show more…

Nicotinamide adenine dinucleotide is an electron carrier used in catabolism. It can be in a reduced (electron-enriched) or oxidized (electron-deficient) form. Identify the following features in the structures below: (nicotinamide C4) (nicotinamide N1) (nicotinamide) (adenine) (diphosphate) (complete molecule) (complete molecule) The reduced form of nicotinamide adenine dinucleotide The part of the molecule that is derived from the vitamin niacin The site where a hydride ion (2e- + H+) will be added

Nearly all enzymes that require a nicotinamide cofactor use either NAD+/NADH or NADP+/NADPH but not both. Compare the net charge of each cofactor.
