Cas no 34620-78-5 (Maltoheptaose)

Maltoheptaose is a linear oligosaccharide composed of seven glucose units linked by α-1,4-glycosidic bonds. It serves as a valuable substrate in enzymatic studies, particularly for amylases and glucosidases, due to its well-defined structure and intermediate chain length. Its high purity and solubility make it suitable for use in biochemical research, including carbohydrate metabolism investigations and enzyme kinetics. Maltoheptaose is also employed in the development of analytical standards for chromatography and mass spectrometry. Its consistent molecular weight and structural homogeneity ensure reliable performance in experimental applications. This compound is commonly utilized in food science and pharmaceutical research for its functional properties as a model starch fragment.
