ketone

 [ke´tōn]
any compound containing the carbonyl group, C=O, and having hydrocarbon groups attached to the carbonyl carbon, i.e., the carbonyl group is within a chain of carbon atoms.
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 of lipid and pyruvate within the liver, and are oxidized by muscles. Excessive production leads to urinary excretion of these bodies, as in diabetes mellitus; see also ketosis. Called also acetone bodies.

ke·tone

(kē'tōn),
Any organic compound in which two carbon atoms are linked by the carbon of a carbonyl group (C-O). The simplest ketone and the most important in medicine is dimethyl ketone (acetone).
