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.or the same reason, carotenoid colors often predominate in ripe fruit after being unmasked by the disappearance of chlorophyll.
