ketone bodies

the substances acetone, acetoacetic acid and β-hydroxybutyric acid; except for acetone (which may arise spontaneously from acetoacetic acid), they are normal metabolic products usually derived from excess acetyl CoA from fatty acids within the liver, and are oxidized by the extrahepatic tissues; excessive production leads to urinary excretion of these bodies, as in diabetes mellitus. Called also acetone bodies. See also ketosis, acetonemia, pregnancy toxemia.
