Carotenoids: functions and fallacies

Many epidemiological studies have demonstrated an association between a high intake of fruits and vegetables and a low risk of diseases, particularly epithelial cancers (Hennekens, 1986). Initially these foods were considered only as a source of retinol, that is vitamin A, since vitamin A-deficient diets have been linked with cancer for almost 60 years (for review, see Moon, 1989). Furthermore,...

Biological activities of natural and synthetic carotenoids: induction of gap junctional communication and singlet oxygen quenching.

Induction of gap junctional communication (GJC) and antioxidant activities of carotenoids have been considered as biochemical mechanisms underlying the cancer-preventive properties of these compounds. beta-Carotene and other carotenoids, including those lacking provitamin A activity, proved to be active in both these parameters. The beta-carotene analogs retrodehydro-beta-carotene, echinenone, ...

Antioxidant activities of astaxanthin and related carotenoids.

The antioxidant activities of astaxanthin and related carotenoids have been measured by employing a newly developed fluorometric assay. This assay is based on 4,4-difluoro-3,5-bis(4-phenyl-1, 3-butadienyl)-4-bora-3a,4a-diaza-s-indacene (BODIPY 665/676) as an indicator; 2,2'-azobis-2,4-dimethylvaleronitrile (AMVN) as a peroxyl radical generator; and 6-hydroxy-2,5,7, 8-tetramethylchroman-2-carbox...
