Xylotetraose is a tetrasaccharide composed of four β-D-xylose units linked by β(1→4) glycosidic bonds. Derived from xylan (a plant hemicellulose) via enzymatic hydrolysis, it is water-soluble and indigestible by humans, reaching the colon intact. As part of xylooligosaccharides (XOS), it acts as a prebiotic, selectively promoting beneficial gut bacteria (e.g., Bifidobacterium). Industrially, it aids in biomass conversion for biofuels and serves as a substrate for enzyme studies (e.g., xylanases). Compared to shorter XOS (e.g., xylobiose), its longer chain may enhance prebiotic efficacy. Used in functional foods for gut health, it bridges sustainable agriculture and biotechnology.
Xylotetraose is a tetrasaccharide composed of four β-D-xylose molecules linked linearly by β(1→4) glycosidic bonds, belonging to the xylooligosaccharides (XOS) family with a degree of polymerization (DP) of 4.
Source:
Produced via enzymatic (e.g., xylanase) or chemical hydrolysis of xylan, a hemicellulose abundant in plant cell walls (e.g., agricultural residues like straw).
Properties:
Water-soluble, stable under acidic conditions and high temperatures.
Resistant to human digestive enzymes, allowing it to reach the colon intact.
Applications:
Prebiotic: Selectively stimulates the growth of beneficial gut bacteria (e.g., Bifidobacteria, Lactobacilli), enhancing gut health.
Biofuel Production: Serves as a fermentable substrate for microbial conversion into biofuels (e.g., ethanol) or biochemicals.
Functional Foods: Incorporated as a dietary fiber or low-calorie sweetener in beverages, dairy products, and supplements.
Biotechnology Research: Used to study enzyme kinetics and substrate specificity of xylan-degrading enzymes (e.g., xylanases, xylosidases).
Significance:
A critical intermediate in biomass valorization, aiding the conversion of lignocellulosic waste into renewable resources.
Compared to shorter XOS (e.g., xylobiose DP2, xylotriose DP3), xylotetraose may exhibit stronger prebiotic effects or unique enzymatic interaction patterns, making it valuable for tailored health and industrial applications.
In summary, xylotetraose bridges sustainable biomass utilization and human health, serving as a multifunctional oligosaccharide in biorefineries, nutrition, and biotechnological research.
