Ketones are the result of oxidation of secundary alcohols.

Explanation:

A secundary alcohol is an alcohol where two other C-atoms are attached to the one having the alcohol (OH) group, like in 2-propanol CH_3-CHOH-CH_3CH3CHOHCH3

When oxidized, the H from the carbon-atom and the H from the OH group combine with O to form water, and the O on the carbon is now double-bonded:
propanon CH_3-CO-CH_3CH3COCH3

This compound cannot be easily oxidized any further.
