What is cellobiose what are its important properties?
Answer Posted / sundaramoorthy
Cellobiose is a disaccharide with the formula
[HOCH2CHO(CHOH)3]2O. The molecule is derived from the
condensation of two glucose molecules linked in a β(1→4)
bond. It can be hydrolyzed by bacteria or cationic ion
exchange resins[1] to give glucose. Cellobiose has eight
free alcohol (COH) groups and three ether linkages, which
give rise to strong -inter- and intra-molecular hydrogen bonds
It can be obtained by enzymatic or acidic hydrolysis of
cellulose and cellulose rich materials such as cotton, jute,
or paper. Cellulose is a polymer of glucose units linked by
β(1→4) bonds.
Treatment of cellulose with acetic anhydride and sulfuric
acid, gives cellobiose tetraacetate, which cannot engage in
hydrogen bonding and is soluble in nonpolar organic solvents.[2]
