	Ketone bodies - Wikipedia, the free encyclopedia
		Ketone bodies are three chemicals that are produced as by-products when fatty acids are broken down for energy.
		The three ketone bodies are acetoacetate, beta-hydroxybutyrate and acetone.
		Ketone bodies are produced from acetyl-CoA (see ketogenesis) mainly in the mitochondria of liver cells when carbohydrates are so scarce that energy must be obtained from breaking down fatty acids.

	Ketone - Wikipedia, the free encyclopedia
		Acetone, acetoacetate and beta-hydroxybutyrate are ketones (or ketone bodies) generated from carbohydrates, fatty acids and amino acids in humans and most vertebrates.
		Ketones are elevated in blood after fasting including a night of sleep, and in both blood and urine in starvation, hypoglycemia due to causes other than hyperinsulinism, various inborn errors of metabolism, and ketoacidosis (usually due to diabetes mellitus).
		Ketones are often used in perfumes and paints to stabilize the other ingredients so that they don't degrade as quickly over time.

	Dorlands Medical Dictionary
		ketone bodies three substances that are produced by fatty acid and carbohydrate metabolism in the liver, being β-hydroxybutyric acid, acetoacetic acid, and acetone in approximately a 78:20:2 ratio.
		a cytoplasmic body of varying appearance, structure, and function closely associated with the nucleus, kinetoplast, and basal body in certain parasitic flagellate protozoa; it is usually connected to the basal body by a fibril or thread, which together are known as the parabasal apparatus.
		an ovoid body found in the adventitia of the upper part of the superior bulb of the internal jugular vein; its structure and presumably its function are similar to those of the glomus caroticum (carotid body).

	Ketone Bodies
		Ketone body synthesis from acetyl CoA occurs in hepatic mitochondria
		Therefore, if the demand for ATP is high the fate of acetyl-CoA is likely to be further oxidation to CO The level of fat oxidation is regulated hormonally through phosphorylation of ACC, which may activate it (in response to glucagon) or inhibit it (in the case of insulin).
		This allows the heart and skeletal muscles primarily to use ketone bodies for energy, thereby preserving the limited glucose for use by the brain.
