Ordering Information

Biological Activity

L-Xylose is a rare monosaccharide and aldopentose enantiomer that serves as a biochemical probe and substrate in carbohydrate metabolic pathways. In fungal systems, L-xylose is processed through a specialized L-xylose catabolic pathway, where it is converted into L-xylulose by L-xylose dehydrogenase. This pentose conversion links sugar transport and enzymatic utilization to downstream cellular metabolism, supporting research into stereospecific carbohydrate pathways and biosynthetic transformations.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
