Cyclic peroxides from a soya lipoxygenase-catalysed oxygenation of methyl linolenate



Cyclic peroxides from a soya lipoxygenase-catalysed oxygenation of methyl linolenate



Biochimica et Biophysica Acta 528(1): 119-126



Incubation of methyl linolenate with an aqueous extract of soyabean flour at neutral pH gives the hydroperoxyendoperoxides 16-hydroxyperoxy-13,15-endoperoxylinolenate and 9-hydroxyperoxy-10,12-endoperoxylinolenate as the principal oxygenation products in addition to monohydroperoxides. Lipoxygenase I (EC 1.13.11.12) does not catalyse the oxygenation under this condition. The enzyme contributing most to the formation of the hydroperoxyendoperoxides is assumed to be a high molecular mass lipoxygenase aggregate.
