what is the major structural difference between the starch amylopectin and glycogen?
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.
