Descrição geral

Xanthophylls are oxygenated derivatives of carotenoids. It consists of oxygen atoms. Xanthophylls are yellow pigments and are found majorly in the leaves of most green plants.

Aplicação

Xanthophyll has been used:
  • to quantify circulating lutein in birds
  • to study its effect on the synthesis of factor D (FD) by adipocytes
  • for the quantification of carotenoids from the leaves of Brassica oleracea

Embalagem

1, 5 mg in glass bottle
Dry powder packed under Argon.

Ações bioquímicas/fisiológicas

Xanthophyll/Lutein functions as an accessory light-harvesting pigment. It also acts as quenchers of singlet oxygen and chlorophyll triplet states to exhibit protection against photooxidative damage. Xanthophyll is involved in photosynthesis. It has antioxidant properties.
Dietary carotenoid with no vitamin A potency. Increases macular pigment concentration in the eye and may improve visual function.

Qualidade

Minimum 70% total carotenoids as xanthophyll.
