Is xanthophyll a chlorophyll?
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 (an excited form of chlorophyll), which is overproduced at high light levels in …
What is carotene and xanthophyll?
The difference between the two groups is chemical: xanthophylls contain oxygen, while carotenes are hydrocarbons and do not contain oxygen. Also, the two absorb different wavelengths of light during a plant’s photosynthesis process, so xanthophylls are more yellow while carotenes are orange.

What are xanthophylls made of?
Xanthophylls are oxidized derivatives of carotenes. They contain hydroxyl groups and are more polar; therefore, they are the pigments that will travel the furthest in paper chromatography. The group of xanthophylls is composed of lutein, zeaxanthin, and α- and β-cryptoxanthin.
