BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Here, vitamin E serves as the primary defense against potentially harmful oxidation reactions (NRC, 1989). In addition to vitamin E, ascorbic acid (vitamin C) is one of the other essential nutrients, assisting in this antioxidant defense system by protecting against lipid peroxidation (Frei et al., 1988).

Detailed explanation-2: -Antioxidants, such as vitamins C and E and carotenoids, may help protect cells from damage caused by free radicals. Other naturally occurring antioxidants include flavonoids, tannins, phenols and lignans. Plant-based foods are the best sources.

Detailed explanation-3: -Vitamin E is a fat-soluble vitamin with several forms, but alpha-tocopherol is the only one used by the human body. Its main role is to act as an antioxidant, scavenging loose electrons-so-called “free radicals”-that can damage cells.

Detailed explanation-4: -Antioxidant nutrients commonly included in the diet such as vitamin E, vitamin C, -carotene, selenium, copper, iron and zinc improve different immune function exhibiting an important protective role in infections caused by bacteria, viruses or parasites.
