Answer
- In its role as an antioxidant, VITAMIN E guards cell membranes, body proteins, DNA, and cholesterol, and thus helps prevent heart disease, cancer, macular degeneration, and other chronic diseases.
Explanation:
vitamin E, is an antioxidant that is very effective in protecting the oxidation of DNA, LDL, and protein against oxidative damage by smoking in vitro ( Baker et al., 1999;Panda et al., 1999). Vitamin protects proteins and other biological molecules from the damaging properties of reactive oxygen species and other free radicals.
