So Amylose is an unbranched polysaccharide that consists of glucose monosaccharides connected via alpha one four glycocitic bond. So the only difference between amylose and glycogen is in amylose, we don't have these alpha one six glycocitic bonds, we only have these alpha one four glycocitic bonds. So this is our example of amylose. Now, again, because of the presence of these alpha one four glycocity bonds, the actual structure of starch will essentially be like a helical structure as a result of these alpha one four glycosytic bonds. So even though in this diagram it looks like it's a linear molecule, it's not actually a linear molecule, because if we redraw these molecules in their chair conformations, we're going to see this helical structure that is formed. Now, the other type of starch molecule is amylopectin.
