Properties and stability
at260 It has the maximum ultraviolet absorption spectrum at nanometers. Through various deaminase enzymes, it accepts a hydrogen atom and an electron from the substrate and becomes a reduced form. E′0=-0.32V. At this time, the pyridine ring is reduced, and since there is maximum absorption at 340 nanometers, the progress of the reaction can be measured. This reaction can also proceed reversibly. ThereforeNAD+ can be used as a common substrate for various deaminase, but it acts between two dehydrogenases. Its presence in trace amounts can catalyze the redox reaction (electron transfer) between the two substrates.
