1,4-β-D-Xylotriitol

货号：O-XTRRD

规格：50 mg

CAS: 116269-52-4
Molecular Formula: C15H28O13
Molecular Weight: 416.4
Purity: > 95%

High purity 1,4-β-D-Xylotriitol for use in research, biochemical enzyme assays and in vitro diagnostic analysis. This compound can be used as a substrate for xylan degrading enzymes such as endo-1,4-β-xylanase or β-xylosidase. Borohydride reduced oligosaccharides can be used in the place of native oligosaccharides when performing enzymatic degradation experiments using reducing sugar assays. The native oligosaccharides cannot be used for this purpose because, being reducing sugars themselves, they generate a large ‘blank’ value in these assays.
