Description

Xylotetraose is a defined oligosaccharide composed of four xylose units, offering a high-purity standard for research and industrial applications. This compound serves as a critical biochemical tool for studying xylanase enzyme activity and as a potential prebiotic or functional food ingredient. It is essential for researchers in enzymology, glycobiology, and for manufacturers in the nutraceutical and specialty chemical sectors seeking well-characterized carbohydrate standards.

Application

• Enzyme Substrate & Research: A precise substrate for the assay and kinetic study of endo-xylanases and other hemicellulase enzymes.
• Biochemical Standard: Used as a high-purity reference standard in chromatography (HPLC, HPAEC-PAD) for the quantification and identification of xylo-oligosaccharides (XOS).
• Prebiotic Research: Investigated for its potential bifidogenic effects and role in modulating gut microbiota as a component of xylo-oligosaccharide mixtures.
• Glycobiology Studies: Employed in research exploring carbohydrate-protein interactions, carbohydrate metabolism, and the structure-function relationships of hemicellulose.
• Food Science: Studied for application as a functional food additive to enhance dietary fiber content and promote digestive health.
• Industrial Bioprocessing: Serves as a model compound for optimizing enzymatic hydrolysis processes in the biorefinery and biofuel industries.
