carotenoid Scientific  

/ kə-rŏt′n-oid′ /

1. Any of a class of yellow to red pigments found especially in plants, algae, and photosynthetic bacteria. Carotenoids generally consist of conjoined units of the hydrocarbon isoprene, with alternating single and double bonds. The carotenoids absorb light energy of certain frequencies and transfer it to chlorophyll for use in photosynthesis. They also act as antioxidants for chlorophyll, protecting it from damage by oxidation in the presence of sunlight. Carotenoids are nutritionally important for many animals, giving flamingoes their color, for example, and also have antioxidant properties. There are many types of carotenoids, including carotenes and xanthophylls.

"We hope to further clarify the structural characteristics of carotenoids that increase quenching efficiency, ultimately enabling the molecular design of pigments that optimize photosynthetic antennae," Fujii said.

From Science Daily

The greater flamingo's pink colouring comes from a diet high in carotenoids - pigments found in algae and invertebrates such as shrimp.

From BBC

This shade, often associated with carrots, sweet potatoes and pumpkins, comes from carotenoids, a class of pigments naturally found in plants.
