Potato tuber lipoxygenase was shown to convert 17(S)-hydro(pero)xydocasahexaenoic acid in 10,17(S)-dihydro(pero)xydocosahexa-4Z,7Z,11E,13Z,15E,19Z-enoic acid (10,17(S)-diHDHA). No traces of 10,17(S)-dihydro(pero)xydocosahexa-4Z,7Z,11E,13E,15Z,19Z -enoic acid were found among the reaction products. It is concluded that a described earlier neuroprotectin D1 (or 10,17(S)docosatriene) a novel and potent anti-inflammatory compound derived from docosahexaenoic acid was, in fact, 10,17(S)-dihydroxydocosahexa-4Z,7Z,11E,13Z,15E,19Z-enoic acid formed through a double lipoxygenation mechanism instead of a previously thought epoxidation/isomerization mechanism.
