Unravelling the chemical basis of the bathochromic shift in the lobster carapace; new crystal structures of unbound astaxanthin, canthaxanthin and zeaxanthin
{{output}}
The crystal structures of the unbound carotenoids, synthetic astaxanthin (3S,3'S:3R,3'S:3R,3'R in a 1:2:1 ratio), canthaxanthin and (3R,3'S, meso)-zeaxanthin are compared with each other and the protein bound astaxanthin molecule in the carotenoprotein, beta-c... ...
