Photochemistry of Retinal visual Pigments Rhodopsin or Visual Purple is a puplish red photosensitive pigment present in the outer segment of the rods ( million rods). It is made up of protein portion, an opsin (scotopsin) combined with an aldehyde of vitamin . It all starts with the visual pigments that are embedded in the membranes of the disks found in the outer segment of the rods. This visual pigment is called rhodopsin and is composed of protein called opsin and a derivative of vitamin A called retinal. In the unexcited state, retinal has a bend in its hydrocarbon chain (cis retinal) and fits.

When an ophthalmologist uses an ophthalmoscope to look into your eye he sees the following view of the retina (Fig. 1). In the center of the retina is the optic nerve, a circular to oval white area measuring about 2 x mm across.

Cronin and Jinks () reviewed structural and spectral aspects of crustacean visual ontogeny and predicted the presence of two receptor classes in some crustacean larvae despite the fact that microspectrophotometry has found only a single visual pigment.

A Dartnall. Ommochrome (or visual pigment) refers to several biological pigments that occur in the eyes of crustaceans and eye color is determined by the ommochromes. Ommochromes are also found in the chromatophores of cephalopods, and in spiders.
Ommochromes are metabolites of tryptophan, via kynurenine and are responsible for a wide variety of colors. Rhodopsin (also known as visual purple) is a light-sensitive receptor protein involved in visual is named after ancient Greek ῥόδον (rhódon) for rose, due to its pinkish color, and ὄψις (ópsis) for sight.
Rhodopsin is a biological pigment found in the rods of the retina and is a G-protein-coupled receptor (GPCR). It belongs to s: RHO, CSNBAD1, OPN2, RP4, rhodopsin. A purple substance in the cell membranes of halobacteria (found in extremely saline environments) during conditions of low oxygen, and consisting of the protein bacteriopsin and retinal, the same carotenoid found in the visual pigments of animals; in response to light, the purple membrane pumps protons out of the cell, providing the energy gradient for synthesis of adeniosine triphosphate.
