Abstract

The radical cations of five dietary carotenoids have been shown to react with dopamelanin (a model of the black eumelanin) and cysteinyldopamelanin (a model of the red/yellow pheomelanin) in both micellar and homogeneous environments. It is suggested that such repair reactions show previously unidentified protective roles for melanin/carotenoid combinations, especially where the maintenance of the (small) carotenoid concentration is vital to avoid deleterious effects, such as in the retina of the eye.
