Polyenes and vision

Chem Biol. 1996 Apr;3(4):255-62. doi: 10.1016/s1074-5521(96)90105-2.


Polyenes are important for vision in all sighted species. The visual pigments (the rhodopsins) all use 11-cis-retinal as the chromophore; some possible reasons for the importance of this isomer are now emerging. New results on the involvement of xanthophils in the maintenance of the retina are also discussed.
