And what that means is the fatty acids will be a much more concentrated form of energy storage than glycogen. In fact, for 1 gram of glycogen, there are about 2 grams of water that associates with that gram of glycogen. Why? Well, because glycogen, which consists of glucose monomers, contains many hydroxyl groups and those hydroxyl groups are polar and so they attract water. And so what that means is glycogen is not a very concentrated form of energy storage like triglycerides are. So we see that the fact that triglycerides are highly reduced and anhydrous dismiss triglycerides, highly compact and highly concentrated stores of metabolic cell energy.
