Circular dichroism and absorption spectra were determined for digitonin extracts of three rhodopsins: cattle, grass frog, and pigeon; and three porphyropsins: channel catfish, bluegill sunfish, and redear sunfish. A comparison of these spectra shows the following: (1) Porphyropsins, like rhodopsins,...
