Hypotaurine is an organic compound known for its antioxidant properties, particularly in research applications. It effectively scavenges free radicals and reactive oxygen species (ROS), crucial agents of oxidative damage to cells and tissues. By donating electrons, hypotaurine neutralizes these harmful radicals, preventing them from causing cellular harm. This action stabilizes ROS and mitigates their ability to induce oxidative stress, crucial for maintaining cellular redox balance. Through these mechanisms, hypotaurine helps preserve cell integrity and function, making it an essential tool in studying the effects of oxidative stress on biological systems.
