Question

Quizplus · Accepted Answer

Beta-carotene is a weaker antioxidant than vitamin E, lycopene, and lutein because it has fewer conjugated double bonds. Conjugated double bonds are responsible for the antioxidant activity of carotenoids, and beta-carotene has only 11 conjugated double bonds, compared to 13 for lycopene and 10 for lutein. Vitamin E is also a more effective antioxidant than beta-carotene because it has a hydroxyl group, which can donate a hydrogen atom to free radicals.
