Answer to Question #109710 in Biochemistry for kylie

Question

Compare and contrast between glycogen and cellulose?

Answer 1

Definition

Cellulose: Cellulose is the main structural component of the cell wall of plants.

Glycogen: Glycogen is the main storage carbohydrate energy source of fungi and animals.    

Monomer

Cellulose: The monomer of cellulose is beta glucose.

Glycogen: The monomer of glycogen is alpha glucose.

Bond Between Monomers

Cellulose: 1,4 glycosidic bonds occur between the monomers of cellulose.

Glycogen: 1,4 and 1,6 glycosidic bonds occur between the monomers of glycogen.

Nature of the Chain

Cellulose: Cellulose is a straight, long, unbranched chain, which forms H-bonds with adjacent chains.

Glycogen: Glycogen is a short, many branched chains of which some chains are coiled. 

Molecular Formula

Cellulose: The molecular formula of cellulose is (C6H10O5)n.

Glycogen: The molecular formula of glycogen is C24H42O21.

Molar Mass

Cellulose: Molar mass of cellulose is 162.1406 g/mol.

Glycogen: Molar mass of glycogen is 666.5777 g/mol.

Found in

Cellulose: Cellulose is found in plants.

Glycogen: Glycogen is found in animals and fungi.

Function

Cellulose: Cellulose is involved in the building of cellular structures like cell walls.

Glycogen: Glycogen serves as a carbohydrate energy store.

Occurrence

Cellulose: Cellulose occurs in fibers.

Glycogen: Glycogen occurs in small granules.
