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. And amylopectin is essentially almost the same as glycogen, because Amylopectin, just like glycogen, contains the alpha one four glycocytic bonds and the alpha one six glycocytic bonds. The only difference between amylopectin and glycogen is that in Amylopectin, these alpha one six glycocitic bonds are less common. In glycogen, these appear every ten or so units, but in starch, in amylopectum, they appear every 30 or so units.
