Question: what are the structural differences between amylose amylopectin glycogen and cellulose?
Answer: Amylopectin is therefore a branched polymer. Glycogen is similar in structure to amylopectin, but branches more frequently. Cellulose is an unbranched polymer composed of beta glucose molecules. Beta glucose is an isomer of glucose in which the hydroxyl group attached to carbon 1 is above the plane of the ring.
