Antioxidant Activity (Cellular Oxidative Stress Pathways) (N/A)
- Target
- N/A
- Molecular classification
- Enzyme, Transcription factor, Small molecule, Signaling pathway
01
Overview
Antioxidant activity in the context of cellular oxidative stress pathways refers to the collective mechanisms by which cells detect, respond to, and neutralize reactive oxygen species (ROS) and other free radicals. These processes are crucial for maintaining cellular homeostasis and preventing damage to proteins, lipids, DNA, and other biomolecules. Oxidative stress occurs when there is an imbalance between ROS production and antioxidant defenses, leading to potential cell dysfunction or death. This target encompasses a network rather than a single molecule/receptor—it includes all molecular systems involved in sensing oxidative imbalance and mounting an adaptive antioxidant response at the cellular level.
