So the complete oxidation of fatty acids yields about 38 kilojoules of gram that we oxidize. And if we compare that to oxidizing, carbohydrates or proteins, this only yields about 17 kilojoules per gram that we actually oxidized. So we're able to actually store much more energy in these fatty acids. And when we break down these triglycerides, we can also actually form many more high energy ATP molecules. Now, within our body, we have different types of cells that can actually store fatty acids. But there are two most important cells because these are the cells that store the predominant number of fat molecules.
