Xanthophylls from the Sea: Algae as Source of Bioactive Carotenoids [PDF]
Marine Drugs, 2021 Algae are considered pigment-producing organisms. The function of these compounds in algae is to carry out photosynthesis. They have a great variety of pigments, which can be classified into three large groups: chlorophylls, carotenoids, and phycobilins.

Factors Differentiating the Antioxidant Activity of Macular Xanthophylls in the Human Eye Retina
Antioxidants, 2021 Macular xanthophylls, which are absorbed from the human diet, accumulate in high concentrations in the human retina, where they efficiently protect against oxidative stress that may lead to retinal damage.

Antioxidant activities of carotenes and xanthophylls [PDF]
FEBS Letters, 1996 The purpose of this study was to assess the relative antioxidant activities of a range of carotenes and xanthophylls through the extent of their abilities to scavenge the ABTS·+ radical cation. The results show that the relative abilities of the carotenoids to scavenge the ABTS·+ radical cation are influenced by the presence of functional groups with ...
