Description

D-Arabinose is a dinucleotide phosphate that is an important metabolic intermediate in the pentose phosphate pathway. It has been shown to have pharmacological effects, such as enzyme inhibition and binding to DNA. D-Arabinose has been used in biochemical studies of energy metabolism and related areas. D-Arabinose is converted to ribitol by ribitol dehydrogenase, which can be oxidized to ribulose 5-phosphate by ribulose 5-phosphate dehydrogenase. The conversion of D-arabinose to ribitol requires NAD(P)H, which provides the reducing power for this reaction. The conversion of ribitol to ribulose 5-phosphate also requires NAD(P)H, but does not produce any reducing power. A redox potential measurement was used to determine the relative reduction potentials of the two reactions and found that they are equal at -0.5 volts (V).
