Xanthophylls were found to be oxidized to unstable keto-carotenoids in mice. These metabolic conversions are thought to affect the levels of bioavailable carotenoids in tissues. In this article, the solubilization into mixed-micelles, intestinal absorption and oxidative metabolism of carotenoids are ...
the intestinal lumen; (c) the uptake of carotenoids into intestinal mucosal cells; (d) the incorporation ofcarotenoids into chylomicrons; (e) the release and transport into the circulation; and (f) the distribution,metabolism, and recycling of carotenoids among tissues. Continued development of ass...

Marine Drugs, Vol. 9, Pages 1024-1037: Absorption and Metabolism of XanthophyllsDietary carotenoids, especially xanthophylls, have attracted significant attention because of their characteristic biological activities, including anti-allergic, anti-cancer, and anti-obese actio ...Dietary c...

HDL metabolismThe antioxidant xanthophylls lutein and zeaxanthin are absorbed from the diet in a process involving lipoprotein formation. Selective mechanisms exist for their intestinal uptake and tissue-selective distribution, but these are poorly understood. We investigated the role of high-density ...

This paper reviews the absorption and metabolism of xanthophylls by introducing recent advances in this field. Keywords: absorption; bioavailability; carotenoid; metabolism; xanthophyll1. Introduction Carotenoids, which are synthesized de novo by microorganisms and plants, accumulate in various biological ...
For example, the carotenes and xanthophylls found in all microalgae (eukaryotes and cyanobacteria), as well as the phycocyanin of cyanobacteria, have potent antioxidant and possibly anticancer effects [20]. The content of photosynthetic units of cells in relation to their pigment composition differs ...
