Properties and stability<\/h2>\n
\n at260<\/SPAN> 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\u20320=-0.32V<\/SPAN>. At this time, the pyridine ring is reduced, and since there is maximum absorption at 340<\/SPAN> nanometers, the progress of the reaction can be measured. This reaction can also proceed reversibly. ThereforeNAD+<\/SPAN> 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. <\/SPAN><\/SPAN>\n <\/p>\n
