So these alpha one four glycocitic bonds, this one, this one, this one, this one, this one, this one and so forth, they basically create this helical structure. And the helical chain has these branching points every ten or so units as a result of these alpha one six glycocitic bonds. And together, this basically gives glycogen a very branched structure. Now, when we want to break down glycogen, we can easily break down glycogen because we have the proteins, the enzymes that are able to break down glycogen into the individual constituents, the glucose molecules. And then we can use the glucose molecules in the process of glycolysis and the crept cycle to basically form the ATP molecules, the energy molecules which are used by our cells. So even though glycogen is not directly used as the energy source, we transform glycogen into something that we can use as an energy source, namely the high energy adenosine triphosphate molecules.
