NAD stands for nicotinamide adenine dinucluotide. NAD+ is the oxidised form, and NADH is the reduced form which exist in an equilibrium, with NAD+ being favoured. Oxidation of fuel molecules produces electrons which are used to reduce NAD+ in the reaction of ethanol + dehydrogenase to form ethanal + NADH + H+. Also NADH+ is oxidised to NAD in oxidative phosphoryation which is directly linked to ATP synthesis [1].
