| | D-Arabinpyranose Usage And Synthesis |
| Chemical Properties | White to off-white powder | | Uses | An inhibitor of the enzyme glucose dehydrogenase. | | Definition | ChEBI: D-arabinopyranose is d-Arabinose in its pyranose form. | | Purification Methods | Crystallise D-(-)-arabinose three times from EtOH, dry it in vacuo at 60o for 24hours and store it in a vacuum desiccator. It also crystallises from a mixture of H2O/MeOH/EtOH with m 158-160o, or H2O with m 160-161o. [Whistler & Schweiger J Am Chem Soc 81 5190 1959, Fletcher et al.
