Antioxidant activities of spray-dried carotenoids using maltodextrin-Arabic gum as wall materials
Bulletin of the National Research Centre, 2021 Background Carotenoids are natural pigments that are highly sensitive to light, heat, acids, oxygen, metals, and free radicals, which degrade the antioxidant activities of carotenoids.

Aromatic carotenoids: Biological sources and geological implications
Geosystems and Geoenvironment, 2022 Aromatic carotenoids have been discovered in geological sections recording mass extinction events, oceanic anoxic events, and other geological abnormalities. Given their conventional biological source attribution to phototrophic sulfur bacteria, aromatic

Bacterial Carotenoids. XLVI. C50-Carotenoids. 14. C50-Carotenoids from Arthrobacter glacialis. [PDF]
Acta Chemica Scandinavica, 1975 From the psychrophilic bacterium Arthrobacter glacialis have been isolated three C50-carotenoids with molecular formulae C50H72O2: the bicyclic decaprenoxanthin (1a, 7% of total carotenoids), the aliphatic bisanhydrobacterioruberin (2a, 10%) and the monocyclic A.g. 470 (3a, 83%).

Understanding/unravelling carotenoid excited singlet states. [PDF]
, 2018 Carotenoids are essential light-harvesting pigments in natural photosynthesis. They absorb in the blue–green region of the solar spectrum and transfer the absorbed energy to (bacterio-)chlorophylls, and thus expand the wavelength range of light that is ...
