Question

What is the major difference among the common polysaccharides glycogen, starch, and cellulose?

Answer 1

Cellulose, starch, and glycogen are polymers of glucose. Difference between them is regarding the presence of glucose and bonds that join or bond the glucose monomers together.

Starch and glycogen are composed of Alpha-glucose. Starch is made up of two various types of polymers which are amylose and amylopectin. Glycogen differs from the starch in the context of branching I.e., It branches more frequently.

Cellulose itself is an unbranched polymer made up of Beta-glucose molecules.
