Product Name:D(+)-Cellobiose
English Name:D(+)-Cellobiose
CAS No.:528-50-7
Aliases:D-Cellobiose, 4-O-β-D-Glucopyranosyl-D-glucopyranose, 4-β-D-Glucopyranosyl-D-glucose
Molecular Formula:C12H22O11
Physical Properties:White crystalline powder. Fine granular crystals can be obtained from aqueous ethanol solution (after vacuum drying). Melting point: 225°C (decomposes). Specific rotation: +36.4° (15 h). It reduces Fehling's solution and exhibits mutarotation in aqueous solution. It is not hydrolyzed by maltase but can be hydrolyzed by emulsin. Freely soluble in water, slightly soluble in ethanol, practically insoluble in ether.
Uses:Cellobiose is the basic structural unit of cellulose and does not occur in free form in nature. Upon hydrolysis, it yields two molecules of D-(+)-glucose and is commonly used as a substrate for assaying β-glucosidase and cellulase activities. It is also employed as a biochemical reagent, chromatographic reference standard, and control substance in carbohydrate metabolism research.
Technical Specifications:
Assay: ≥98%
Molecular weight: 342.30
Melting point: 225°C (decomposes)
Specific rotation: +36.4° (15 h)
Solubility: freely soluble in water, slightly soluble in ethanol, practically insoluble in ether
