Description

D-Xylobiose is a disaccharide composed of two xylose units, serving as a fundamental structural unit of xylan and hemicellulose. This compound is crucial for research in carbohydrate chemistry, enzymology, and the development of functional foods and prebiotics. It is primarily utilized by researchers in biotechnology, pharmaceutical development, and the food science industries to study glycoside hydrolases, gut microbiota modulation, and as a standard for analytical purposes.

Application

• Biochemical Research Standard: Used as a high-purity reference standard in HPLC, LC-MS, and enzymatic assays for carbohydrate analysis.
• Enzyme Substrate & Inhibitor Studies: Serves as a specific substrate for studying the activity and kinetics of xylanases, β-xylosidases, and other glycoside hydrolases.
• Prebiotic & Nutraceutical Research: Investigated for its potential to selectively stimulate the growth of beneficial gut bacteria (e.g., Bifidobacteria) in functional food and dietary supplement development.
• Glycobiology & Cell Wall Research: Essential for studying the structure, biosynthesis, and degradation of plant hemicellulose and microbial polysaccharides.
• Pharmaceutical Intermediate: Acts as a building block or chiral precursor in the synthesis of more complex glycoconjugates and bioactive molecules.
• Food Science: Used in research to understand sweetness perception, non-digestible carbohydrates, and as a potential low-calorie sweetener or texturizer.
