[Free radical lipid oxidation and physical properties of lipid layer of biological membranes].
Biofizika 1987 Sep-Oct; 32(5):830-44B

Abstract

The results obtained mainly by the author and coworkers are summarized. One efficient method to detect free radicals in biological samples is chemiluminescence (CL). In the absence of activators CL of membraneous systems is due to lipid peroxide free radicals, whereas in the presence of luminol it is initiated by oxygen radicals. Low levels of free radicals in the cells and blood plasma are maintained by antioxidants, enzymes included. Ferrous ions increase free radical concentrations in the cells and tissues. Deleterious action of hydroxyl radicals is the result of the breakage of DNA strains and of lipid peroxidation (LPO). The latter reaction brings about the damage of the membrane barriers due to a decrease of the electrical stability of the membrane lipid bilayer and "self-breakdown" of the membranes by potential differences produced in the living cells.
