Rhodopsin is the light-absorbing pigment of the rods. It is incorporated in the membranes of disks that are neatly stacked (some 2000 of them) in the outer portion of the rod. Full article >>>
rhodopsin [Gk. rhizoma, mass of roots] A visual pigment consisting of retinal and opsin. When rhodopsin absorbs light, the retinal changes shape and dissociates from the opsin, after which it is converted back to its original form. Full article >>>
rhodopsin Light-sensitive substance that occurs in the rods of the retina; visual purple. rhombogen Stage in the life cycle of a dicyemid mesozoan. Full article >>>
(I've recently stumbled onto a reference that claims that vertebrate rhodopsin and bacteriorhodopsin are not part of the same gene family. I'll reserve judgement until I've read more than just the abstract of the paper. Full article >>>
We have exploited this knowledge to develop efficient in vitro lipid-bilayer folding systems for the membrane protein, bacteriorhodopsin. Full article >>>
