Question

what is NAD+

Answer 1

NAD is a shortnen for Nicotinamide Adenine Dinucleotide and works as a major electron carrier in the oxidation of fuel molecules.

Answer 2

It is a coenzyme that acts as an electron carrier by accepting two electrons and a stabilizing hydrogen ion to form NADH.

Answer 3

The reactive part of NAD+ is its nicotinamide ring, a pyridine derivative synthesized from the vitamin niacin. In the oxidation of a substrate, the nicotinamide ring of NAD accepts a hydrogen ion and two electrons, which are equivalent to a hydride ion (H-) the reduced from of this carrier is called NADH.
