Redox homeostasis is the balance between oxidants and antioxidants in the body, maintaining stability in the redox reactions. Oxidants are molecules that can generate free radicals, while antioxidants are molecules that neutralize free radicals. This balance is crucial for cellular function and overall health, as imbalances can lead to oxidative stress and damage to cells, proteins, and DNA. Research in redox homeostasis explores the mechanisms by which cells regulate and maintain this balance, as well as the impact of oxidative stress on various diseases and aging processes. Studies in redox homeostasis aim to develop strategies for promoting antioxidant defenses and reducing oxidative damage to improve health outcomes.
