Question

This consists of mostly linear strands.

• A. Starch
• B. Glycogen
• C. Cellulose
• D. Fibrin

Answer 1

Answer: (C)

Cellulose

Starch exists in two forms known as amylose and amylopectin. Amylose is a linear poly-D-glucose in which the monosaccharides are connected by alpha 1, 4 linkages. Amylopectin has alpha 1, 4-glycosidic linkages with side chain branching of alpha 1,6 linkage.

Glycogen consists of long polymer chains of glucose units connected by an alpha acetal linkage. It has alpha 1,6 branching pattern.

Cellulose is a polysaccharide. It is a linear structure formed by the linkage of beta 1,4 linkage of the glucose unit.

Fibrin is a non-globular protein involved in the clotting of blood. The chains of fibrin are internally linked by hydrogen bond. It has branched stacked structure.

So, the correct answer is option C.
