Biological Activity	12-HPETE generated by 12-lipoxygenase is enzymatically converted to bioactive compounds such as leukotriene and HETE Spector_AA et al..
Genetic Information
Note	Isomerization of hydroperoxides : Both 5- and 15-hydroperoxide were generated predominantly by autooxidation or singlet-oxygen mediated oxidation Terao_J et al. Yamagata_S et al. Peers_KE et al.. However, the proportion of each isomer generated become almost equal by supplementation of hydrogen donor such as tocopherol Porter_NA et al. Terao_J et al. Peers_KE et al..
