β-NAD+, a pyridine nucleotide and biologically active form of nicotinic acid, is a coenzyme necessary for the catalytic reaction of certain enzymes. β-NAD+ is a carrier for hydride ion, forming β-NADH. Hydride ion is enzymatically removed from a substrate molecule by the action of dehydrogenases such as malic dehydrogenase and lactic dehydrogenase. Such enzymes catalyze the reversible transfer of a hydride ion from malate or lactate to β-NAD+ to form the reduced product, β-NADH. Unlike β-NAD+ which has no absorbance at 340 nm, β-NADH absorbs at 340 nm. The increase in absorbance at 340 nm with the formation of β-NADH is the basis for measurement of activity of many enzymes.
