Chemical Modifications of Biomolecules by Oxidants
There is strong evidence in support of the oxidation of biomolecules during normal physiology and under conditions of environmental or pathological...
-
Superoxide Dismutases and Catalase
Superoxide dismutases (SODs) and catalase represent the primary enzymatic defense against reactive oxygen species. Both enzymes are present in...
-
Protein Repair and Degradation
Protein oxidation is one of the important processes taking place during oxidative stress. Numerous amino acids can be modified within proteins...
