Physicochemical Information
Autooxidation of icosapentaenoate Yamauchi_R et al.. Oxidation of icosapentaenoate by singlet-oxygen Yamauchi_R et al.. Oxidation of icosapentaenoate in the presence of myoglobin.
Isomerization of hydroperoxides generated from icosapentaenoete by autooxidation: the proportion of 5-, 18-isomer (outer hydroperoxides) is higher than that of other isomer (8-,9-,11-,12-,14-,15-isomer[inner hydroperoxides]).
