Chemiluminescence of Soybean Seeds: Spectral Analysis, Temperature Dependence and Effect of Inhibitors

Abstract: Abstract— The spontaneous light emission of soybean seeds is enhanced 4–8 times during the first minute after water imbibition. Other solvents are also effective. The temperature dependence of soybean chemiluminescence identifies two reactions with activation energies of 20 and 68 kJ/mol corresponding to the lipoxygenase reaction and to the autoxidation of unsaturated fatty acids, respectively. Free radical scavengers and lipoxygenase inhibitors decrease soybean photoemission. The singlet oxygen probe 1,4‐dia… Show more

“…Both processes have been identified on the basis of their Arrhenius activation energies (8). The peroxy-radicals from unsaturated fatty acids are intermediates of the autooxidation process whereas the lipoxygenase reaction yields peroxy-radicals in a side reaction (8,11,15). The predominantly red emission is consistent with 1o22 being one of the species responsible for photoemission (8,10).…”

“…Soybean seeds show spontaneous low level chemiluminescence, which sharply increases upon imbibition (6,8). Two processes, the nonenzymic autooxidation of unsaturated fatty ' Supported by grants acids and the lipoxygenase-catalyzed reaction (8), lead, through common intermediates (ROO') to light emission. Both processes have been identified on the basis of their Arrhenius activation energies (8).…”
