Nah, not quite correct. Isoketals may still be formed and do harm even
outside a cell, and chances are even increased that arachidonic acid
will meet such a non-enzymatically fate outside the cell, where oxygen
molecules may react with the cyclic form of it.

Most probably, many physiological/biochemical effects of arachidonate
not explainable by eicosanoids are due to the forming of isoketals and
alike :-(

(See isoketals, isoneurals and isofurans on PubMed, or do search for
isolevuglandins and levuglandins.
