Fig. 2. Schematic of ketone body (KB) formation. 3-Hydroxybutyrate, a KB, is produced from the oxidation of fatty acids, resulting in the production of acetyl CoA. Acetyl CoA is consequently converted into HMG-CoA and then to acetoacetate which is the precursor to 3-hydroxybutyrate. Figure and caption adapted from [5].
