In larger plants, there are three carotenoid pigments which might be active in the xanthophyll cycle: violaxanthin, antheraxanthin, and zeaxanthin. During mild stress, violaxanthin is converted, i.e. reduced, to zeaxanthin via the intermediate antheraxanthin, which plays a direct photoprotective position performing as a lipid-protective anti-oxidant and by stimulating non-photochemical quenching within gentle-harvesting proteins. In diatoms and dinoflagellates, the xanthophyll cycle consists of ...
