General description

D-(+)-Melezitose monohydrate is a crystalline form of the trisaccharide compound known as melezitose. Melezitose is composed of three glucose molecules linked together in a specific arrangement. It is commonly found in certain plants, such as cotton and buckwheat, as well as in the honeydew produced by some insect species. This compound can be used in various applications, including as a reference standard in analytical chemistry or as a component in research and development studies. It is also used in biochemical studies for investigating the metabolism and enzymatic activities related to sugars and carbohydrates.

Application

D-(+)-Melezitose monohydrate finds applications in various fields, including analytical chemistry, research and development, biochemical studies, and food industry. D-(+)-Melezitose can be used to identify clinical isolates of indole-positive and indole-negative Klebsiella spp.
