Beta carotene is an antioxidant. The polyene chain is the structural feature of all the carotenoids eg. Beta carotene(provitamin A) . This feature determines the chemical nature of carotenoids towards free radicals.
Selenium is a strong antioxidant. They work by neutralising excess free radicals in the body . Thus it protects cells from damaging by oxidative stress.
Vitamin C and E acts as an antioxidant. They give free electrons to the free radicals,this extra electron stabilizes them . Thus it prevents them from causing further damage to the cells of the body.
