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. First, let's actually discuss how we form these ketone bodies. So we have four important steps in the formation of ketone bodies. So in step number one, let's suppose we have low levels of OXYL acetate, high levels of acetyl coenzyme a.
