NAD+/ NADHNAD+ (Nicotinamide Adenine Dinucleotide) functions as an electron acceptor in catabolic pathways.
The nicotinamide ring of NAD+, which is derived from the vitamin niacin, accepts 2 e- and one H+ (a hydride) in going to the reduced state, as NAD+ becomes NADH
The electron transfer reaction may be summarized as:
NAD+ + 2 e- + H+ <-> NADHIt may also be written as:
NAD+ + 2 e- + 2H+ <-> NADH + H+
