Web6 de fev. de 2024 · Ketone bodies formed during ketogenesis The principal ketone bodies, 3-β-OHB and acetoacetate, are transported from the liver to tissues where they are used as a source of energy. The brain is an organ that relies on ketones in states of relative carbohydrate deficiency, as it is unable to break down fatty acids itself. 1 Ketone bodies are water-soluble molecules or compounds that contain the ketone groups produced from fatty acids by the liver (ketogenesis). Ketone bodies are readily transported into tissues outside the liver, where they are converted into acetyl-CoA (acetyl-Coenzyme A)—which then enters the citric acid cycle (Krebs cycle) and is oxidized for energy. These liver-derived ketone groups include acetoacetic acid (acetoacetate), beta-hydroxybutyrate, and acetone, a spontaneou…
