Xanthophylls from the Sea: Algae as Source of Bioactive Carotenoids
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.

How Do Xanthophylls Protect Lipid Membranes from Oxidative Damage?
Here, we address the problem of the antioxidant activity of carotenoids in biomembranes. The activity of lutein and zeaxanthin in the quenching of singlet oxygen generated by photosensitization was monitored in lipid vesicles using a singlet oxygen ...

Background: Oxidative stress contributes to pathogenesis and progression of Alzheimer’s disease (AD). Higher levels of the dietary antioxidants— carotenoids and tocopherols— are associated with better cognitive functions and lower risk for AD, and lower ...

Factors Differentiating the Antioxidant Activity of Macular Xanthophylls in the Human Eye Retina
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.

Excited States of Xanthophylls Revisited: Toward the Simulation of Biologically Relevant Systems
Xanthophylls are a class of oxygen-containing carotenoids, which play a fundamental role in light-harvesting pigment–protein complexes and in many photoresponsive proteins. The complexity of the manifold of the electronic states and the large sensitivity

Free Radical Mediated Oxidative Degradation of Carotenes and Xanthophylls
This article reviews the excited-state quenching, pro-vitamin A activity and anticarcinogenicity of carotenes and xanthophylls in relation to their chemical structures.

Sea Buckthorn Oil as a Valuable Source of Bioaccessible Xanthophylls
Sea buckthorn oil, derived from the fruits of the shrub, also termed seaberry or sandthorn, is without doubt a strikingly rich source of carotenoids, in particular zeaxanthin and β-carotene.
