Description

.Alpha.-D-Glucan CAS NO 9074-78-6 is a polysaccharide composed of glucose units linked primarily by α-glycosidic bonds. This compound is valued for its role as a model substrate in enzymatic studies and as a functional biopolymer in various industrial processes. It is essential for researchers and manufacturers in the biotechnology, pharmaceutical, and food science sectors seeking consistent, high-purity carbohydrate materials.

Application

• Enzymatic Substrate: Used as a standard substrate for the assay and characterization of α-amylase, glucoamylase, and other starch-degrading enzymes.
• Biochemical Research: Serves as a critical reagent in carbohydrate metabolism studies, glycobiology research, and the development of diagnostic kits.
• Pharmaceutical Excipient: Investigated for use as a binder, filler, or controlled-release matrix in tablet and capsule formulations.
• Food Science: Applied in research to study starch retrogradation, texture modification, and as a prebiotic fiber source.
• Industrial Biotechnology: Acts as a feedstock or intermediate in the fermentation and biocatalytic production of sugars, organic acids, and biofuels.
• Reference Standard: Utilized as a high-purity calibrant or reference material in analytical laboratories for chromatography (HPLC, HPAEC-PAD) and spectroscopy.
