A role for &bgr;,&bgr;-xanthophylls in Arabidopsis UV-B photoprotection

Journal of Experimental Botany, 2018
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.

Understanding the Changes in the Circular Dichroism of Light Harvesting Complex II upon Varying Its Pigment Composition and Organization [PDF]

, 2007
In this work we modeled the circular dichroism (CD) spectrum of LHCII, the main light harvesting antenna of photosystem II of higher plants. Excitonic calculations are performed for a monomeric subunit, taken from the crystal structure of trimeric LHCII ...

The kinetics of colour degradation, chlorophylls and xanthophylls loss in pistachio nuts during roasting process

Food Quality and Safety, 2019
Colour is amongst the parameter which is used for process control during roasting. In this study, the effects of hot air roasting temperature (120, 130, 145, 160, and 170°C) and hot air velocity (0.6, 1.3, and 2 m/s) on colour change ...

The impact of selected xanthophylls on oil hydrolysis by pancreatic lipase: in silico and in vitro studies

Scientific Reports
Lipase inhibition is one of the directions to control obesity. In vitro assays have confirmed the inhibitory effect of selected xanthophylls, including astaxanthin, fucoxanthinol, fucoxanthin, and neoxanthin.

Mechanisms of selective delivery of xanthophylls to retinal pigment epithelial cells by human lipoproteins

Journal of Lipid Research, 2016
The xanthophylls, lutein and zeaxanthin, are dietary carotenoids that selectively accumulate in the macula of the eye providing protection against age-related macular degeneration.

Reviewing the effects of food provisioning on wildlife immunity [PDF]

, 2018
While urban expansion increasingly encroaches on natural habitats, many wildlife species capitalize on anthropogenic food resources, which have the potential to both positively and negatively influence their responses to infection.

Differential Roles of Carotenes and Xanthophylls in Photosystem I Photoprotection.

Biochemistry, 2016
Carotenes and their oxygenated derivatives, xanthophylls, are structural elements of the photosynthetic apparatus and contribute to increasing both the light-harvesting and photoprotective capacity of the photosystems.

A protective effect of anthocyanins and xanthophylls on UVB-induced damage in retinal pigment epithelial cells.

Food & Function, 2016
Increased exposure to solar ultraviolet B (UVB) radiation causes oxidative damage that may promote age related macular degeneration (AMD) and other ocular pathologies.

Effects of Dietary Paprika Xanthophylls on Ultraviolet Light-Induced Skin Damage: A Double-Blind Placebo-Controlled Study.

Journal of Oleo Science, 2018
Generation of singlet oxygen by solar ultraviolet (UV) radiation causes acute inflammatory responses in the skin. Accumulation of singlet-oxygen-quenching antioxidants in the skin can suppress this photo-oxidative stress.

Revisiting the Role of Xanthophylls in Nonphotochemical Quenching.

Journal of Physical Chemistry Letters, 2018
Photoprotective nonphotochemical quenching (NPQ) of absorbed solar energy is vital for survival of photosynthetic organisms, and NPQ modifications significantly improve plant productivity.
