Antioxidant processes

Antioxidant processes refer to a collection of biochemical pathways and actions by which cells inhibit oxidation and neutralize free radicals, minimizing damage to vital biomolecules including DNA, proteins, and lipids. These processes involve a wide array of enzymes (such as superoxide dismutase, catalase), small molecules (such as glutathione, ascorbic acid, vitamin E), and dietary phytonutrients. Antioxidant defenses are critical for maintaining cellular homeostasis, particularly under conditions of increased metabolic activity, environmental stress, or inflammation. Disruption of antioxidant processes or excessive oxidative stress is implicated in the pathophysiology of various diseases, including cancer, cardiovascular disease, neurodegenerative disorders, and aging-related conditions. However, "antioxidant processes" as a term does not denote a singular druggable target but a fundamental aspect of cellular physiology and biochemistry. In summary, "antioxidant processes" is not an individual molecular target; instead, it encompasses systems and pathways involved in oxidative stress management. For structured database purposes, this entry should be excluded or flagged due to lack of specificity.
