1. Xanthophyll

   Xanthophylls (originally phylloxanthins) are yellow pigments that occur widely in nature and form one of two major divisions of the carotenoid group; the other division is formed by the carotenes. The name is from Greek xanthos (ξανθός, "yellow") and phyllon (φύλλον, "leaf"), due to their formation of the yellow band seen in early chromatography of leaf pigments.

1. xanthophyll

   Xanthophyll is a type of yellow to orange pigment found in plants and some types of algae. It is a class of oxygen-containing carotenoid pigments, responsible for the color of autumn leaves and the yellow color in egg yolks. Xanthophylls are essential in the processes of photosynthesis and are involved in the protection of plant tissues from the damaging effects of excess light. Plant xanthophylls include lutein and zeaxanthin, both of which are important for human eye health.

1. Xanthophyll

   Xanthophylls are yellow pigments that form one of two major divisions of the carotenoid group. The name is from Greek xanthos and phyllon, due to their formation of the yellow band seen in early chromatography of leaf pigments. Their molecular structure is similar to carotenes, which form the other major carotenoid group division, but xanthophylls contain oxygen atoms, while carotenes are purely hydrocarbons with no oxygen. Xanthophylls contain their oxygen either as hydroxyl groups and/or as pairs of hydrogen atoms that are substituted by oxygen atoms acting as a bridge. For this reason, they are more polar than the purely hydrocarbon carotenes, and it is this difference that allows their separations from carotenes in many types of chromatography. Typically, carotenes are more orange in color than xanthophylls. Like other carotenoids, xanthophylls are found in highest quantity in the leaves of most green plants, where they act to modulate light energy and perhaps serve as a non-photochemical quenching agent to deal with triplet chlorophyll, which is overproduced at high light levels in photosynthesis. The xanthophylls found in the bodies of animals, and in dietary animal products, are ultimately derived from plant sources in the diet. For example, the yellow color of chicken egg yolks, fat, and skin comes from ingested xanthophylls.
