Healthy bodies make all the NADH they need using vitamin B3 also known as niacin, or nicotinamide as a starting point. The NAD coenzyme acts as a hydrogen acceptor in oxidation-reduction reactions.
The electron transport chain in cellular respiration is responsible for energy production and is an excellent illustration of NAD's involvement in redox reactions. In cells, most oxidations are accomplished by the removal of hydrogen atoms. NAD coenzyme plays a crucial role in this. However, only one proton accompanies the reduction.
The other proton produced as two hydrogen atoms are removed from the molecule being oxidized is liberated into the surrounding medium. Would you like to start shopping?
