Description

D-Celloheptaose is a defined, high-purity oligosaccharide derived from cellulose, specifically a heptamer of D-glucose units linked by β(1→4) glycosidic bonds. This compound serves as a critical reference standard and biochemical tool for research into cellulose structure, enzymatic degradation, and carbohydrate metabolism. It is essential for scientists and manufacturers in the biotechnology, pharmaceutical research, and specialty chemical sectors who require precise molecular tools for analytical calibration, enzyme substrate studies, and the development of novel biomaterials.

Application

• Enzyme Substrate & Assay Development: Used as a specific substrate for studying the activity, kinetics, and inhibition of cellulases, β-glucosidases, and other carbohydrate-active enzymes.
• Chromatographic Reference Standard: Serves as a high-purity calibration standard in HPLC, HPAEC-PAD, and other analytical methods for oligosaccharide separation and quantification.
• Biochemical Research: A key tool for investigating cellulose biosynthesis, degradation pathways, and the interactions between carbohydrates and proteins.
• Nutritional & Microbiome Studies: Employed in research on dietary fiber, prebiotic effects, and fermentation processes by gut microbiota.
• Material Science: Used in the development and characterization of advanced biomaterials, hydrogels, and nano-cellulose derivatives.
