Description

Glucuronoxylan is a naturally occurring hemicellulose polysaccharide, a key structural component of plant cell walls. Its unique composition of xylose backbone with glucuronic acid side chains provides valuable functional properties for advanced material science and life science applications. This biopolymer is essential for researchers and manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries seeking sustainable, bio-based materials.

Application

• Pharmaceutical Excipient: Used as a binder, disintegrant, or controlled-release matrix in tablet and capsule formulations.
• Biomedical Research: Serves as a substrate or model compound for studying plant cell wall biosynthesis, degradation, and enzymatic activity.
• Nutraceutical & Functional Food Ingredient: Explored as a source of prebiotic dietary fiber and for its potential health-beneficial properties.
• Biomaterial & Hydrogel Formation: A precursor for creating biocompatible films, coatings, and hydrogels for tissue engineering and wound care.
• Enzymology & Biochemistry: A specific substrate for assaying the activity of xylanases, glucuronidases, and other carbohydrate-active enzymes.
• Specialty Chemical Synthesis: Used in the derivatization and production of novel bio-based polymers and chemicals.

Quality Control

Our Glucuronoxylan is produced and tested to ensure high purity and batch-to-batch consistency suitable for research and development. While specific grades are available, all materials are characterized for key parameters such as uronic acid content, degree of substitution, and molecular weight distribution. A comprehensive Certificate of Analysis (COA) detailing purity, identification, and physical specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). For long-term storage, consider desiccated conditions to maintain stability.
