Description

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

Application

• Chromatographic Reference Standard: Primary use as a high-purity calibrant and system suitability standard for HPLC, HPAEC-PAD, and GC analysis of starch hydrolysates and oligosaccharides.
• 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.
• Food Science & Nutrition Research: Employed in research on dietary fiber, prebiotic effects, starch digestion rates, and the glycemic index of complex carbohydrates.
• Pharmaceutical Excipient Development: Investigated for its potential as a novel excipient in drug formulation, particularly in stabilizing biopharmaceuticals or as a component in controlled-release matrices.
• Biochemical Reagent: Serves as a defined oligomer for studying carbohydrate-protein interactions, cell signaling pathways, and the biosynthesis of glycans.
• Quality Control in Starch Industry: Acts as a critical benchmark for profiling the oligosaccharide composition and degree of polymerization in maltodextrins, syrups, and modified starches.
