Purpose. The role carotenoids play in human health is not well understood. Carotenoids are antioxidants that react with free radicals. Molecules called free radicals form during normal cell metabolism and with exposure to ultraviolet light or toxins such as cigarette smoke.arotenoids are highly colored red, orange, and yellow pigments found in many vegetables. A German scientist isolated the first carotenoid in 1826 from carrots and named it beta-carotene. Since then, more than 600 carotenoids have been identified in plants, algae, fungi, and bacteria.
