Question: what is the major structural difference between the starch amylopectin and glycogen?
Answer: Amylopectin and glucogen are two types of branched polysaccharides. The main difference between amylopectin and glycogen is that amylopectin is an insoluble form whereas glycogen is a soluble form. Amylopectin is one of the two types of starch, which is the main form of storage polysaccharides in plants.
