ABSTRACT
Physiological role of copper complexes includes many functions and a special place occupies participation in lipid oxidation of biological membranes. Chain oxidation of ethyl oleate in micellar solution in the presence of copper (II) complexes with 伪-alanine as a catalyst were decomposed. The results obtained indicated parallel of formation and decomposition of primary and secondary products in catalytic lipid oxidation. We proposed mechanism of catalytic lipid oxidation, based on the results obtained and well-known kinetic scheme. Possibility of participation of copper (I and II) not only in the decomposition of primary hydroperoxides, but secondary oxidation products such as 伪, 尾-unsaturated carbonyl compounds are discussed. Activation energies of formation and decay of lipid peroxidation products were calculated. The results obtained were (71卤1) and (58卤1) kJ/mol, respectively. The assays described herein are similarity to biological systems.
