Abstract

Antioxidants are any substances that delay the oxidation of proteins, carbohydrates, lipids, and DNA at low concentrations. Antioxidants are compounds that can prevent cell damage caused by molecules called free radicals. Free radicals are produced by natural physiological processes such as metabolism but can also be produced by environmental factors such as pollution, radiation, and cigarette smoke. When free radicals accumulate in the body, they cause oxidative stress that can damage cells, proteins, and DNA. Antioxidants are naturally found in various food sources such as fruits, vegetables, grains, and dairy products. Synthetic antioxidants are synthesized in laboratories, and in some cases, they show more antioxidant activity, but caution should be taken while using these compounds due to their toxicity. This article investigates antioxidants, the processes related to them, the defense mechanism of antioxidants, and types of antioxidants.
