It will follow the pathway we call ketonogenesis, the formation of ketone bodies. So once again, acetal Co enzyme A, generated via the beta oxidation of fatty acids, can only be used to form ATP via the citric acid cycle if we have enough oxyloacetate inside the cell. So if our carbohydrate intake is low, for example, we're fasting or in diabetics, and we'll talk more about diabetics and ketogenesis in the next lecture. The liver will use up the majority of the oxalo acetate to help generate glucose via glucaneogenesis. And by driving the oxalo acetate levels to the ground, what that basically means is those acetyl coenzyme A molecules will be diverted to a different pathway known as ketogenesis, the formation of ketone bodies. Now, ketone bodies are actually energy fuel molecules, and we'll talk about that in just a moment.
