Abstract

Arachidonic metabolism with the lipoxygenase to form its hydroperoxides (eicosanoids) has been commonly known in animal. Recently, we reported that eicosanoids, 12(S)- and 15(S)- hydroperoxyeicosatetraenoic acid were the intermediate product of major aldehyde flavor formation [3(Z)- and 2(E)- nonenal and n-hexanal] in an edible brown alga, Laminaria angustata via lipoxygenase (LOX) and hydroperoxide lyase pathway. Here another eicosanoides have been found after enzymatic formation and identified as 11-, 9-, 8- hydroperoxyeicosatetraenoic acid by HPLC and GC/GC-MS. They are believed to be the intermediate of physiological active compounds involving in chemical defense and sex pheromone. These represented the mechanism of positional selectivity of LOX in this marine alga.
