| Hazard Information | Back Directory | [Description]
D-Xylose is a five-carbon sugar that contributes to lignocellulose in plants. It is predominantly found in hardwoods and agricultural residues. | [Uses]
Diagnostic aid (intestinal function determination）. | [Application]
D-Xylose has been used:- as one of the component to stimulate microbial activity;
- for the enhancement of biofilm formation;
- as a part of biochemical tests for the identification of B. cereus group;
- for substrate screening characterization.
| [Definition]
ChEBI: Alpha-D-xylose is a D-xylopyranose in with an alpha-configuration at the anomeric position. It has a role as an algal metabolite. | [Brand name]
Xylo-Pfan (Savage). | [Biochem/physiol Actions]
Estimation of D-Xylose in the urine after oral administration, is useful in diagnosing absorption of carbohydrates and malabsorption of non-pancreatic molecules. D-Xylose plays a significant role in the biologically conversion of plant biomass to fuels and chemicals. | [Synthesis]
In a process for the production of D-xylose from a ligno-cellulosic material comprising an xylan-containing hemicellulose by the steps of:
(1) hydrolysing the ligno-cellulosic material with an aqueous acid to produce an aqueous xylose-containing medium and an insoluble residue comprising lignin;
(2) separating the insoluble residue from the xylose-containing medium;
(3) treating the xylose-containing medium to remove organic and/or ionic contaminants therefrom;
(4) concentrating the xylose-containing medium to a syrup; and
(5) mixing the syrup with an alcohol to form an alcoholic solution and crystallizing xylose from the alcoholic solution. |
