Description

Arabinoheptaose is a defined oligosaccharide composed of seven arabinose units, a key structural component in plant-derived polysaccharides like arabinoxylans and pectins. This high-purity reference standard is critical for analytical research, enabling precise calibration and method validation in carbohydrate analysis. It serves as an essential tool for researchers and quality control laboratories in the food science, nutraceutical, and plant biochemistry sectors, supporting the development and standardization of analytical protocols for complex carbohydrate matrices.

Application

• Analytical Reference Standard: Primary use as a high-purity calibrant for HPLC, HPAEC-PAD, and GC-MS analysis of arabinose-containing polymers.
• Food Science Research: Studying the structure-function relationships of dietary fibers, arabinoxylans, and prebiotic components.
• Enzyme Substrate & Assay Development: Used as a specific substrate to characterize the activity of arabinanases, arabinofuranosidases, and other glycosyl hydrolases.
• Pharmaceutical & Nutraceutical R&D: Investigating the biological activity and metabolic pathways of oligosaccharides for potential health applications.
• Plant & Agricultural Biochemistry: Research into plant cell wall architecture, biosynthesis, and degradation processes.
• Quality Control & Method Validation: Ensuring accuracy and precision in the quantitative analysis of arabino-oligosaccharides in raw materials and finished products.
