[Determination of the mechanism of action of antioxidants in lipid systems from chemiluminescence in the presence of ferrous oxide].
Different action mechanisms of antioxidants affecting various stages of chemoluminescence developing in the lipid systems with ferrous ions are considered theoretically. Experimental studies are carried out on beta-naphtol and 5-oxitriptamine--antioxidants whose action mechanism in other systems has been investigated. It is concluded while comparing the experimental data with theoretical concepts that beta-naphtol in mitochondria and liposome suspensions binds the radicals according to the "sticking" mechanism, while 5-oxitriptamine reduces hydroperoxides.
