What is the Major Structural Difference Between Starch and Glycogen

Question

What is the major structural difference between starch and glycogen?
A)The types of monosaccharide subunits in the molecules.
B)The type of glycosidic linkages in the molecule.
C)Whether glucose is in the α or β form.
D)The amount of branching that occurs in the molecule.
E)They have different amounts of hydrogen bonding.

Accepted Answer

The major structural difference between starch and glycogen is that glycogen has more branching than starch. Glycogen has more frequent branching (every 10 to 12 glucose units) than starch (every 20 to 25 glucose units). This makes glycogen a more compact molecule with a higher storage capacity.
