| D(+)-Xylose Usage And Synthesis |
Chemical Properties | white crystals or powder | Chemical Properties | D-Xylose is nearly odorless and has a smoky flavor. This compound is an aldopentose monosaccharide. | Uses | D-Xylose is used in diagnostic malabsorption tests as well as in the production of Furfural. | Uses | In tanning, dyeing, and as a diabetic food. | Uses | sweetener, pharmaceutical intermediate | Definition | A SUGAR that has five
carbon atoms in its molecules. | Definition | ChEBI: The pyranose form of D-xylose. | Brand name | Xylo-Pfan (Savage). | General Description | Xylose is a five-carbon sugar that contributes to lignocellulose in plants. Xylose is predominantly found in hardwoods and agricultural residues. | Biochem/physiol Actions | Estimation of xylose in the urine after oral administration, is useful in diagnosing absorption of carbohydrates and malabsorption of non-pancreatic molecules. Xylose plays a significant role in the biologically conversion of plant biomass to fuels and chemicals. | Purification Methods | -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.
