Metabolic profile of linoleic acid in porcine leukocytes through the lipoxygenase pathway.

Porcine neutrophilic leukocytes were found to contain a lipoxygenase which converted linoleic acid into 13-hydroxy-9,11-octadecadienoic acid (n-6 specificity), arachidonic acid into 12-hydroxy-5,8,10,14-eicosatetraenoic acid (n - 9 specificity) and 5-hydroxy-6,8,11,14-eicosatetraenoic acid into 5,12-dihydroxy-6,8,10,14-eicosatetraenoic acid. This lipoxygenase was partially purified and it appeared that its substrate specificity and other properties were quite different from the 12-lipoxygenase of blood platelets. Incubations of intact or broken porcine leukocytes with added linoleic acid revealed the formation of not only 13-hydroxy-9,11-octadecadienoic acid but also of substantial amounts of epoxyhydroxy and trihydroxy isomers. These products from linoleate, collectively described by the name 'octadecanoids' were characterized in detail by a combination of chemical, chromatographic and mass spectrometric techniques. The phospholipids of porcine leukocytes contain more than twice as much linoleate than arachidonate (22 vs. 8%). In accordance with this fatty acid composition we found that in the stimulated neutrophil the endogenous production of octadecanoids often surpassed that of the eicosanoids. Lipoxygenation of endogenously liberated linoleic acid was especially pronounced when a suspension of leukocytes in citrated plasma was recalcified and allowed to clot.[1]
