Description

D-(+)-Cellobiose is a disaccharide that is comprised of two units in beta (1-4) glycosidic linkage. The compound is generated from the partial hydrolysis of cellulose. It is noteworthy that cellobiose is an exogenous carbohydrate that is generated from the breakdown of plant material (cellulose) such as paper, cotton, or jute. It is neither metabolized in the body nor produced by the body, but can be obtained from food products such as fruits, vegetables, and corn syrups.

Alpha-cellobiose is a cellobiose with an alpha-configuration at the anomeric position.

Crystalline

The product of the partial hydrolysis of cellulose, composed of two d-glucose molecules.

Cellobiose is a disaccharide, commonly classified as a reducing sugar. It is mostly produced as an intermediate in the hydrolysis of the polysaccharide cellulose.

D-(+)-Cellobiose Use and Manufacturing

D-(+)-Cellobiose is commonly used as a carbohydrate indicator for intestinal permeability in Crohn’s disease and malabsorption syndrome. When treated with sulfuric acid and acetic anhydride, cellulose generates cellobiose tetraacetate, which is soluble in nonpolar solvents and cannot engage in hydrogen bonding. Bacteriology.

Bacteriology.

D-(+)-Cellobiose is used to differentiate bacteria based on carbohydrate fermentation abilities. It is a β-glucosidase substrate. Also used as as a chemical raw material and for foods, as a low-sweetness sugar.
