title: [Relation between activity of antioxidants and oxidation of substrates in natural lipids].
abstract: Using chemiluminescence method, the oxidation level of lipids extracted from various organs and tissues of fish Coregonus peled (Gmelin) was investigated. The analysis of interrelation between the oxidation level, quantity and composition of phospholipids (PL), fatty acids (FA), natural antioxidants (NAO) was carried out. The oxidation level of the lipids under investigation is shown to increase in series: first go internal fat lipids, then--lipids of brain, white muscles, immature eggs, red muscles, liver. The lipid oxidation level was found to correlate with the quantity of PL, fraction content of phosphatidylethanolamine and cardiolipin, and concentration of the sum of polyunsaturated FA with the index of (20:5 divided by 22:6). It is shown that there is a regularity in the process of distribution in lipids both the sum of natural inhibitors, and individual AO, such as tocopherol, ubiquinone, ubichromenol, the quantity of which increases in accordance with the rising oxidation level of lipid substrate.
