Description

D-(+)-Cellopentaose is a well-defined, high-purity oligosaccharide consisting of five 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, and advanced materials sectors who require precise molecular tools for analytical method development, enzyme activity assays, and the study of complex polysaccharide systems.

Application

• Biochemical Research & Standard: Used as a high-purity reference standard in HPLC, LC-MS, and other analytical techniques for the quantification and characterization of cellulosic materials and enzymatic hydrolysates.
• Enzyme Substrate & Assay Development: Serves as a specific substrate for studying the activity, kinetics, and inhibition of cellulases, β-glucosidases, and other carbohydrate-active enzymes.
• Carbohydrate Chemistry & Synthesis: Acts as a key intermediate or building block in the chemical and enzymatic synthesis of more complex glycoconjugates, labeled probes, or novel biomaterials.
• Nutritional & Microbiome Studies: Employed in research investigating prebiotic effects, gut microbiota fermentation, and the metabolic pathways of dietary fibers.
• Pharmaceutical Excipient Research: Utilized in studies exploring the use of cello-oligosaccharides in drug delivery systems for their potential binding and carrier properties.
