It is a member of the class of carotenoids known as xanthophylls. They are split into two classes, xanthophylls and carotenes. Violaxanthin and zeaxanthin are carotenoid molecules within the chloroplasts called xanthophylls. The antenna pigments are predominantly chlorophyll "b", xanthophylls, and carotenes. Lycopene is a key intermediate in the biosynthesis of beta-carotene and xanthophylls. Besides chlorophyll, plants also use pigments such as carotenes and xanthophylls. Xanthophylls, especially the orange-red zeaxanthin, are also common. As the chlorophylls degrade, the hidden pigments of yellow xanthophylls and orange beta-carotene are revealed. It gives rise to the xanthophylls diatoxanthin and dinoxanthin. Lycopene is a key intermediate in the biosynthesis of carotenoids, such as beta-carotene, and xanthophylls. Egg yolks gain their color from xanthophylls, also a type of carotenoid pigment. Carotenoids containing some oxygen are known as xanthophylls. Xanthophylls are often yellow, hence their class name. In white cultivars, carotenoids are formed, while in red cultivars, anthocyanins and xanthophylls are formed. Xanthophylls are found in all young leaves and in etiolated leaves.
