Description

Maltoheptaose Hydrate 90 is a defined linear oligosaccharide consisting of seven glucose units linked by α-1,4 glycosidic bonds. This high-purity, well-characterized carbohydrate standard is critical for research and industrial applications requiring precise molecular weight and structural reference materials. It is primarily utilized by analytical laboratories, biotechnology firms, and food science researchers for method development, calibration, and as a substrate in enzymatic studies.

Application

• Chromatography Standard: Serves as a precise calibration standard in High-Performance Liquid Chromatography (HPLC) and Size-Exclusion Chromatography (SEC) for analyzing complex carbohydrate mixtures.
• Enzyme Substrate & Research: Used as a specific substrate to study the activity, kinetics, and inhibition of enzymes like α-amylase, glucoamylase, and other starch-degrading enzymes.
• Biochemical & Nutritional Research: Employed in metabolic studies to investigate carbohydrate digestion, glycemic response, and prebiotic potential in model systems.
• Food Science & Quality Control: Acts as a reference material for quantifying maltooligosaccharide profiles in syrups, beers, and starch hydrolysates to ensure product consistency.
• Pharmaceutical Excipient Development: Investigated for its potential use as a stabilizer, carrier, or taste-masking agent in novel drug formulations.
