Description

Maltoheptaose is a well-defined linear oligosaccharide consisting of seven glucose units linked by α-1,4 glycosidic bonds. This high-purity carbohydrate standard is critical for research and industrial applications requiring precise calibration and reference material. It serves as an essential tool for scientists and quality control professionals in the biotechnology, pharmaceutical, and food science sectors, enabling accurate analysis of enzymatic activity, carbohydrate structure, and product composition.

Application

• Chromatography Standard: Used as a primary reference standard in High-Performance Liquid Chromatography (HPLC) and Gel Permeation Chromatography (GPC) for the calibration and quantification of maltooligosaccharides and related polymers.
• Enzyme Substrate & Research: Serves as a specific substrate for studying the kinetics and mechanisms of amylases, glucoamylases, and other starch-degrading enzymes.
• Biochemical Reagent: Employed in the development of diagnostic kits and assays for carbohydrate metabolism research and clinical analysis.
• Food Science & Nutrition: Utilized in research on starch digestion, glycemic index studies, and the development of functional foods and prebiotics.
• Pharmaceutical Excipient Development: Investigated for its potential as a carrier or stabilizer in novel drug delivery systems due to its well-defined structure and biocompatibility.
