Chemische Eigenschaften
white crystals or powder
Verwenden
D-Xylose is used in diagnostic malabsorption tests as well as in the production of Furfural.
Definition
ChEBI: The pyranose form of D-xylose.
Allgemeine Beschreibung
Xylose is a five-carbon sugar that contributes to lignocellulose in plants. Xylose is predominantly found in hardwoods and agricultural residues.
l?uterung methode
-D(+)-Xylose forms needles or prisms (which have a very sweet taste) by slow crystallisation from aqueous 80% EtOH or absolute EtOH, which are then dried at 60o in vacuo over P2O5. Store it in a vacuum desiccator over CaSO4. 1Gram dissolves in 0.8mL H2O. [Bragg & Hough J Chem Soc 4347 1957, Hudson & Yanovsky J Am Chem Soc 39 1029 1917, Monroe J Am Chem Soc 41 1002 1919, Beilstein 1 IV 4223.] In D2O at 31o, 1H NMR showed the following ratios: -pyranose (36.5), -pyranose (63), -furanose + -furanose (~1) [Angyal Adv Carbohydr Chem 42 15 1984, Angyal & Pickles Aust J Chem 25 1711 1972].
