Xanthophylls are oxygenated carotenoids abundant in the human food supply. Lutein, zeaxanthin, and cryptoxanthin are major xanthophyll carotenoids in human plasma. The consumption of these xanthophylls is directly associated with reduction in the risk of cancers, cardiovascular disease, age-related macular degeneration, and cataract formation ...

Survey of Ophthalmology, 2005
The macular pigments are predominantly composed of three carotenoids: lutein, zeaxanthin, and meso-zeaxanthin. These carotenoids are concentrated and distributed in a selective manner. The properties of these pigments are further explored along with their methods of uptake, stabilization, and storage.

Cation radicals of xanthophylls
Photosynthesis Research, 2007Carotenes and xanthophylls are well known to act as electron donors in redox processes. This ability is thought to be associated with the inhibition of oxidative reactions in reaction centers and light-harvesting pigment-protein complexes of photosystem II (PSII).

Xanthophyll Esters in Human Skin
Archives of Biochemistry and Biophysics, 1998Carotenol fatty acid esters in various fruits and vegetables are sources of carotenoids for humans and are cleaved during intestinal absorption to yield the parent xanthophyll. In the present study we demonstrate that low amounts of carotenol esters are present in human skin.

Xanthophyll: Health benefits and therapeutic insights
Life Sciences, 2020Xanthophylls constitute a major part of carotenoids in nature. They are an oxidized version of carotenoid. Xanthophyll has widely drawn scientists' attentions in terms of its functionality, bioavailability and diversity. An assortment of xanthophyll varieties includes lutein, zeaxanthin, β-cryptoxanthin, capsanthin, astaxanthin, and fucoxanthin ...

Among all the carotenoids which are present in the photosynthetic membranes of higher plants, only three undergo rapid, light-induced changes in their concentration. These are the three xanthophylls of the xanthophyll cycle and they undergo intercon versions induced by changes in light intensity. Furthermore, the acclimation of photosynthetic organs to
