Labster enzyme kinetics.

The enzyme ADH from this case requires the co-factor Nicotinamide Adenine Dinucleotide, NAD +, in order to function. This co-factor takes up a hydride ion (H -) from the ethanol, leading to the formation of an acetaldehyde. NAD + is reduced to NADH and thereby works as an electron acceptor (see figure 1). NAD + is derived from the vitamin niacin.
