D-Arabinopyranose

Description:

D-Arabinopyranose is a six-membered cyclic form of the sugar D-arabinose, which is an aldopentose. It is characterized by its molecular formula, which consists of five carbon atoms, twelve hydrogen atoms, and six oxygen atoms. D-Arabinopyranose exists predominantly in its pyranose form in solution, where it adopts a chair conformation that minimizes steric hindrance. This sugar is a white crystalline solid that is soluble in water, reflecting its polar nature due to the presence of multiple hydroxyl (-OH) groups. D-Arabinopyranose plays a significant role in various biological processes and is involved in the synthesis of polysaccharides and glycoproteins. It is also utilized in the food industry and in biochemical research. The compound exhibits reducing sugar properties, allowing it to participate in Maillard reactions, which are important in food chemistry. Additionally, its stereochemistry contributes to its reactivity and interactions with enzymes and other biomolecules.

D-Arabinose

CAS: 28697-53-2

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).
