Health impact of marine carotenoids

Major nutritional effects of astaxanthin, such as cardio-, skin-, and ocular-protective effects, are based on its in vivo antioxidant activity, however, the antioxidant activity of fucoxanthin is not largely involved in its characteristic nutritional activity and anti-obesity andanti-diabetic effects.

The relative antioxidant activities of plant-derived polyphenolic flavonoids.

The relative antioxidant activities, against radicals generated in the aqueous phase, of a range of plant-derived polyphenolic flavonoids, constituents of fruit, vegetables, tea and wine, have been assessed and compounds such as quercetin and cyanidin have antioxidant potentials four times that of Trolox, the vitamin E analogue.

Antioxidant defense systems: the role of carotenoids, tocopherols, and thiols.

The ability of the lipid-soluble carotenoids to quench singlet molecular oxygen may explain some anticancer properties of the carOTenoids, independent of their provitamin A activity.

Scavenging of Nitrogen Dioxide, Thiyl, and Sulfonyl Free Radicals by the Nutritional Antioxidant -Carotene (*)

Mechanisms of free radical scavenging by the nutritional antioxidant β-carotene have been investigated by pulse radiolysis and rate constants for thiyl radical-addition reactions vary from 106 to 109M s and correlate with the lipophilicity of the thiyle radical under study.

Carotene-oxygen radical interactions.

All-trans beta-carotene radical anion efficiently transfers an electron to oxygen but the reverse reaction is not observed and, instead, the formation of a beta- carotene-superoxide radical addition complex is suggested which may be related to the anti-cancer properties of these molecules.
