text: # Triketone
  
  In organic chemistry, a triketone or trione is an organic compound containing three ketone (>C=O) groups. The simplest triketones, such as cyclopropanetrione and 2,3,4-pentanetrione, are only of occasional theoretical interest. More pertinent are triacetylmethane and 2,4,6-heptanetrione. Both species exist predominantly in the enol (C=CH) forms.

  ## Occurrence and significance
  
  Tri- and polyketones are of practical importance as intermediates in the biosynthesis of polyketides. These natural products are a major source of antibiotics.
