Free Radical Formation in Novel Carotenoid Metal Ion Complexes of Astaxanthin
The carotenoid astaxanthin forms novel metal ion complexes with Ca(2+), Zn(2+) and Fe(2+). MS and NMR measurements indicate that the two oxygen atoms on the terminal cyclohexene ring of astaxanthin chelate the metal to form 1:1 complexes with Ca(2+) and Zn(2+) at low salt concentrations < 0.2 mM....
