Carotenoids are organic pigments that are found in the chloroplasts and chromoplasts of plants and some other photosynthetic organisms, including some bacteria and some fungi. Carotenoids can be produced from fats and other basic organic metabolic building blocks by all these organisms. Carotenoids with molecules containing oxygen, such as lutein and zeaxanthin, are known as xanthophylls. 2  The unoxygenated (oxygen free) carotenoids such as Î±-carotene, Î²-carotene, and lycopene, are known as carotenes.
