Final answer:

Amylopectin is the highly branched type of starch that makes up about 80% of digestible starch in the diet.

Step-by-step explanation:

The highly branched type of starch that comprises about 80% of digestible starch in the diet is amylopectin.

Amylopectin is a branched polysaccharide consisting of glucose monomers connected by a-1 → 4 and a-1 → 6 glycosidic linkages. It is the chief carbohydrate present in plants and serves as a main source of dietary energy for humans.

For example, amylopectin can be found in natural starches, and it gives a blue color when reacted with iodine. On the other hand, amylose is a coiled and unbranched starch chain, cellulose is a structural polysaccharide found in plant cell walls, and glycogen is a highly branched form of starch found in animals.
