Aberrant oxidation of biomolecules (AOB) is defined as the covalent oxidation of biomolecules, such as lipids, nucleic acids, and proteins, caused either by a direct oxidation induced by radical and non-radical oxidizing species or by an indirect reaction involving the secondary reactive by-products...

This Section provides a forum for basic, translational, and clinical studies related to antioxidants, ROS, RNS and RSS, and redox signaling in human health and disease. The focus of this Section is on new insights into redox biology and medicine as well as novel therapies and drugs.

Dear Colleagues, The increasing consumer awareness regarding the use of natural antioxidants has led to exploring new natural sources of these compounds. As such, by-products obtained from the agri-food industry constitute an important source of natural antioxidants. Prior to commercialization at...

Antioxidants show the ability to inhibit autoxidation by preventing the formation of free radicals or interrupting their propagation according to different mechanisms. They can be classified as primary antioxidants, chelators, O2•− quenchers, oxygen scavengers, and antioxidant regenerator...

The last decade has seen an upsurge in research into cellular redox processes, from the identification of new reactive species involved in intracellular redox signaling and new redox pathways to diverse dietary and medical interventions. In part, these developments have been fueled by a better under...
