Abstract
This paper reveals for the first time studies of lipid peroxidation and the antioxidant effect of NaCl. The purpose of this study was to determine the antioxidant effect of NaCl using aqueous solution, emulsified, and enzymic lipid peroxidation, and to follow the mechanisms to determine how they occur. The effects of NaCl were confirmed to exist in all systems and to have the same antioxidizing effect.
The mechanism of antioxidant action were as follows:
LH+NaCl+O2→LOO·+HCl+Na+
LOO·+LH→LOOH+L·
LOOH+HCILH→LO·+H2O+Cl-
Linoleic acid (LH) combines with oxygen, which produces peroxy radicals (LOO·), while NaCl dissociates Na+ and Cl- at the same time. Then hydrogen is removed from LH and combines with the peroxy radicals, which produces hydroperoxide (LOOH). Peroxy radicals are then produced again. Thus, there can be a chain reaction, which causes LOOH to accumulate. Once a certain amount of LOOH accumulates, LH can also react with oxygen and Cl-, which produces HCl. The HCl can then react with LOOH and produce H2O. In that reaction, LOOH accepts and decomposes. The study thus offers important findings for lipid biochemistry and sciences.
