Xylose
Based on 5 publication(s) in Google Scholar
Xylose (D-(+)-Xylose) is a natural pentose sugar that is catalyzed by xylose isomerase to form xylulose, which is a key step in the anaerobic ethanol fermentation of Xylose. Xylose can be used by microorganisms to produce fuels, chemicals, and bulk industrial enzymes. Xylose provides the substances and energy for cells, as a carbon source for the biosynthesis of high-value chemicals and biofuel. Xylose can be used to fully explore lignocellulose resources and provide a new direction for microbia fermentation.

Biological Activity
|
Human Endogenous Metabolite |
Xylose (0-90 g/L, 0-48 h) utilization is improved by rapid growth of K. pneumoniae HR521 LDH[1].
Xylose (0-90 g/L, 0-72 h) utilization ratio is 99.1% at 48 hours when the initial acetic acid concentration is 4.5 g/L, and this ratio exceeded 99% at 72 hours when the initial acetic acid concentration is over 2.5 g/L in K. pneumonia[1].
Xylose is converted into xylulose by different enzymes in various microorganisms. In bacteria isomerization of Xylose to xylulose is catalyzed by Xylose isomerase (Xl), whereas yeast and mycelial fungi need a two-step pathway employing D-Xylose reductase (XR) and xylitol dehydrogenase (XDH) [4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Solvent & Solubility
H2O : ≥ 50 mg/mL (333.04 mM)
DMSO : 50 mg/mL (333.04 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
