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, . Visual pigment, any of a number of related substances that function in light reception by animals by transforming light energy into electrical (nerve) potentials.. It is believed that all animals employ the same basic pigment structure, consisting of a coloured molecule, or chromophore (the carotenoid retinal, sometimes called retinene), and a protein, or opsin, of moderate size.

With the identification and structural characterization of several visual pigments has come a new era of investigation. The above comparisons of amino acids sequences predict specific functional domains that may be tested to tell us how visual pigments function to absorb light Cited by:
2. Molecular evolution of cone visual pigments. As described above, vertebrate rod and cone visual opsins, form a phylogenetic sister group with other opsin groups such as the pinopsin, VA opsin, parapinopsin, and parietopsin Fig. 2, we show these groups as having simultaneously diverged, because unambiguous determination of the phylogenetic relationship among these five Cited by: visual pigments: the photopigments in the retinal cones and rods that absorb light and initiate the visual process. This volume is the ideal companion to Wiley's trilogy: The Pigments Handbook (), Industrial Organic Pigments (), and Industrial Inorganic Pigments (). High Performance Pigments have become increasingly important in recent years, with a growth rate well in advance of the more classical types of pigments. The book offers both producers and users of High Performance Pigments the 5/5(1). Apart from rhodopsin, most vertebrate retinas also contain other visual pigments, which are located in the outer segments of the cones. The cone pigments are concerned with color-sensitive daylight vision, while the rods subserve night vision. This chapter discusses the spectral characterization of visual pigments and the structure of : Colin M. Kemp.
