Free radical scavengers, also known as antioxidant agents or antioxidants, are molecules that neutralize and inhibit the harmful effects of free radicals in the body. Free radicals are unstable and highly reactive atoms or molecules that possess an unpaired electron in their outer shell. These unpaired electrons seek stability by reacting with other molecules in the body, leading to oxidative stress and damage to cells, proteins, and DNA.
Free radical scavengers act by donating an electron to the free radicals, thereby neutralizing them and preventing them from causing damage. Additionally, they can also help to regenerate other antioxidants and protect them from being oxidized themselves.
There are several types of free radical scavengers found naturally in the body, such as enzymes like superoxide dismutase, catalase, and glutathione peroxidase. Additionally, there are many antioxidants found in our diet, including vitamins A, C, and E, beta-carotene, and minerals like selenium and zinc. Consuming foods rich in these antioxidants or taking antioxidant supplements can help replenish and enhance the body's natural defense system against free radicals.
The importance of free radical scavengers lies in their ability to maintain cellular health and prevent various diseases associated with oxidative stress, including cardiovascular diseases, cancer, and aging-related conditions. By counteracting the damaging effects of free radicals, free radical scavengers play a crucial role in promoting overall health and well-being.
