Crayfish eye extracts contain two visual pigments resembling in spectrum vertebrate rhodopsin and iodopsin. In these crayfish, as in primates, the “iodopsin” appears to be the red sensitive ...

The only action of light on the pigment of cone vision, iodopsin, as on the rod pigment rhodopsin, is to isomerize its chromophore from 11-cis to all-trans. All further changes are “dark ...

Cone cells operate under photopic conditions (daytime, bright light, and color vision), which constitute a substantial portion of our vision. However, most of our understanding of the visual process ...

FIGURE 1.Chemical structures of the most common chromophore configurations in the rhodopsin families. The type-2 pigments contain an 11-cis, 15-anti retinylidene Schiff base of retinal A1 (A) in the ...
