Antioxidant enzymes are a group of enzymes that help the body to combat oxidative stress and prevent damage caused by free radicals. These enzymes play a crucial role in maintaining cellular homeostasis and protecting cells from damage caused by reactive oxygen species (ROS). Some important examples of antioxidant enzymes include superoxide dismutase, catalase, and glutathione peroxidase. Research in this area focuses on understanding the mechanisms by which antioxidant enzymes function, their regulation, and their potential roles in preventing or treating diseases associated with oxidative stress, such as cancer, neurodegenerative disorders, and cardiovascular disease. Additionally, studies explore potential therapeutic strategies for enhancing the activity of antioxidant enzymes as a means of promoting overall health and well-being.
