Ketoisanic acid is a linear fatty acid composed of 18 carbon atoms, with two triple bonds in the positions 9≡10 and 11≡12, a double bond in the position 17=18, and a ketone substituent in the position 8. This is one of the rare polyacetylenic acids with conjugated triple bonds, the oxygenated isanic acid.[1]
Natural occurrence
The acid can be detected, at concentrations of 1–3%, together with isanic and isanolic acid, in the seed oil of the tree Ongokea gore or Ongokea klaineana; both are plants from equatorial Africa, called "isano" in the local language.[2][3][4]
