CAS 34620-78-5

maltoheptaose

Description:

Maltoheptaose is a carbohydrate composed of seven glucose units linked together by α(1→4) glycosidic bonds, making it a member of the maltooligosaccharides family. It is a non-reducing sugar, meaning it does not have a free aldehyde or ketone group capable of participating in redox reactions. Maltoheptaose is typically produced through the enzymatic hydrolysis of starch by amylase enzymes, which break down larger polysaccharides into smaller oligosaccharides. This compound is soluble in water, and its solubility increases with temperature. It has a sweet taste, although less sweet than glucose or sucrose. Maltoheptaose serves various functions in food and pharmaceutical industries, including as a sweetener, a source of energy, and a bulking agent. Additionally, it can be utilized in research and analytical chemistry for studying carbohydrate metabolism and enzyme activity. Its CAS number, 34620-78-5, is a unique identifier that facilitates its identification in scientific literature and regulatory documents.
