And let's begin by discussing the breakdown of fatty acids. So the breakdown of fatty acids basically consists of four steps. We have an oxidation step, we have a hydration step, we have another oxidation step, and we have a cleavage. And so these four processes together make up one cycle of fatty acid breakdown. And this process is, in fact, an oxidative process. So what we're essentially doing is we're extracting electrons, and we ultimately want to basically cleave a Sigma bond.
