The metabolic fate of arachidonic acid applied to potato tuber slices

Abstract

The metabolism of arachidonic acid (AA) and other selected fatty acids by potato (Solanum tuberosum) tuber slices was followed with the use of radioactive labeled substrates. The predominant metabolites observed were glyceries. Significant quantities of the unmetabolized acids were also recovered. None of the expected AA metabolites such as hydroperoxides or cyclopentenones that are produced by cell-free systems could be detected under the incubation conditions. The elicitor activity of the fatty acids could not be correlated with their rate of metabolism.
