Description

Maltooctaose is a well-defined linear oligosaccharide composed of eight glucose units linked by α-1,4 glycosidic bonds. This high-purity carbohydrate standard is critical for analytical research and method development in the life sciences. It serves as an essential reference material for scientists and quality control professionals in the pharmaceutical, biotechnology, and food science industries requiring precise calibration and validation.

Application

• Chromatography Reference Standard: Primary use as a high-purity calibrant for HPLC, HPAEC-PAD, and other analytical methods for carbohydrate analysis.
• Enzyme Substrate & Kinetics Studies: Used as a specific substrate to study the activity, specificity, and inhibition of enzymes like α-amylase, glucoamylase, and other starch-degrading enzymes.
• Biochemical Research: Serves as a model compound for investigating starch digestion, glycogen metabolism, and the properties of α-glucans.
• Food Science & Nutrition: Employed in research on dietary fiber, prebiotic effects, and the glycemic impact of complex carbohydrates.
• Pharmaceutical Excipient Development: Investigated for its potential functional properties in drug formulation and delivery systems.
• Quality Control & Method Validation: Essential for verifying the accuracy and precision of analytical methods in QC labs for products containing maltooligosaccharides.
