Description générale

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.

Application

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

Actions biochimiques/physiologiques

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.

Conditionnement

Dry powder packed under Argon.

Qualité

Minimum 70% total carotenoids as xanthophyll.

Retinoic Acid and Gene Expression

All-trans retinoic acid (RA, ATRA) is a pleiotropic activation factor that regulates genes associated with normal vertebrate cellular processes such as cell differentiation, cell proliferation, apoptosis, and embryonic development.

Dietary Antioxidants

Antioxidants protect biological systems from oxidative damage produced by oxygen-containing free radicals and from redoxactive transition metal ions such as iron, copper, and cadmium.
