Plots of the molecules viewed down the planes of the polyene chains (a) of the s-cis conformer of astaxanthin diacetate, s-cis-(1); only the higher-occupancy disordered component is shown and solvent molecules are omitted for clarity; (b) of the s-trans conformer of astaxanthin diacetate, s-trans-(1); only the higher-occupancy disordered component is shown; (c) of (3S,3′S)-7,8-didehydroastaxanthin (2); only the higher-occupancy disordered component is shown; (d) of (3S,3′S)-7,8,7′,8′-tetradehydroastaxanthin, (3). |
