Xanthophylls: potential benefits in protecting against UV burns [PDF]
Exposure to ultraviolet (UV) radiation is a significant risk factor for sunburn (solar erythema) and skin cancer. Current treatments focus primarily on symptom relief, making the need for new therapeutic approaches urgent.

Localization and Orientation of Xanthophylls in a Lipid Bilayer
Xanthophylls (polar carotenoids) play diverse biological roles, among which are modulation of the physical properties of lipid membranes and protection of biomembranes against oxidative damage.

We previously found that mice fed lutein accumulated its oxidative metabolites (3′-hydroxy-ε,ε-caroten-3-one and ε,ε-carotene-3,3′-dione) as major carotenoids, suggesting that mammals can convert xanthophylls to keto-carotenoids by the oxidation of ...

Spectroscopic response of carotenoids in chromoplasts in sunflower inflorescence [PDF]
Abstract The vibrant yellow color of the common sunflower (Helianthus annuus L.) ray flower ligules comes from the presence of xanthophylls. The dyes contained by chromoplasts of globular shape were identified in LC-MS studies as lutein derivatives ...

Zeaxanthin and Other Carotenoids: Roles in Abiotic Stress Defense with Implications for Biotic Defense [PDF]
Xanthophylls are carotenoids with diverse roles in stress protection across all taxa of life. This review highlights chloroplast-localized xanthophylls (with a focus on zeaxanthin) of plants by presenting an overview of the protective effects of ...

A role for &bgr;,&bgr;-xanthophylls in Arabidopsis UV-B photoprotection [PDF]
Plastidial isoprenoids, such as carotenoids and tocopherols, are important anti-oxidant metabolites synthesized in plastids from precursors generated by the methylerythritol 4-phosphate (MEP) pathway.

Marine bacteria belonging to genera Paracoccus and Brevundimonas of the α-Proteobacteria class can produce C40-type dicyclic carotenoids containing two β-end groups (β rings) that are modified with keto and hydroxyl groups.

The roles of specific xanthophylls in photoprotection. [PDF]
Xanthophyll pigments have critical structural and functional roles in the photosynthetic light-harvesting complexes of algae and vascular plants. Genetic dissection of xanthophyll metabolism in the green alga Chlamydomonas reinhardtii revealed functions for specific xanthophylls in the ...
