Description

Isomaltotriose is a specific trisaccharide carbohydrate composed of three glucose units linked by α-1,6 glycosidic bonds. This unique structure makes it a valuable oligosaccharide for research and development in life sciences and functional food applications. It serves as a critical standard, substrate, or intermediate for enzymology studies, carbohydrate analysis, and the development of novel prebiotics and sweeteners. Industries including biotechnology, pharmaceuticals, and nutraceuticals rely on high-purity isomaltotriose for precise analytical and formulation work.

Application

• Biochemical Research Standard: Used as a high-purity reference standard in HPLC, LC-MS, and enzymatic assays for carbohydrate analysis and metabolic pathway studies.
• Enzymology Substrate: Serves as a specific substrate for studying the activity and kinetics of enzymes like α-glucosidase, isoamylase, and dextranase.
• Prebiotic Development: Investigated as a potential prebiotic ingredient to selectively promote the growth of beneficial gut microbiota.
• Functional Food & Beverage R&D: Explored as a low-glycemic, functional sweetener or texturizing agent in specialized nutritional products.
• Pharmaceutical Intermediate: Utilized in the synthesis of more complex carbohydrates or glycoconjugates for therapeutic applications.
• Microbial Culture Media: Acts as a defined carbon source in fermentation media for the cultivation of specific microorganisms.

Quality Control

Our Isomaltotriose is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with detailed results from methods including HPLC, optical rotation, and loss on drying. Specifications are designed to meet the rigorous demands of research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect purity and stability.
