Significance of the Malondialdehyde (MDA) Bioassay Methods in Lipid Peroxidation
Abstract: Along with all the metabolic reactions, the cell cytoplasm is engaged in the process of production of the free radicals and reactive oxygen species (ROS). The overproduction of reactive oxygen species in cell cytoplasm leads into the condition of the oxidative stress. This situation may also be the results of the combination of excessive formation of radicals derived from oxygen or nitrogen or both. Cellular components may be attacked in …
