H. Kleszczynska et J. Sarapuk, THE ROLE OF COUNTERIONS IN THE PROTECTIVE ACTION OF SOME ANTIOXIDANTSIN THE PROCESS OF RED-CELL OXIDATION, Biochemistry and molecular biology international, 46(2), 1998, pp. 385-390
A number of new surfactants with an incorporated antioxidant functiona
l group were synthesized in order to be used as agents protecting biol
ogical and/or model membranes against lipid peroxidation. Hydrophobic
parts of these amphiphilic antioxidants ensured their incorporation in
to the membranes studied, viz. pig erythrocytes. Proper concentrations
of the antioxidants were used to avoid erythrocyte membrane destructi
on during the experiments. The work contains the results of studies on
the protective effect of two groups of antioxidants. They differed in
the chain length incorporated into the membrane hydrophobic part and
in the kind of counterion (chloride and bromide). The role of these fa
ctors in the protective action of the compounds studied is discussed a
s well as their practical application.
