1. Chromophore

   Linked via "retinal molecule"

   A chromophore is a molecular feature or group of atoms within a molecule responsible for the color of that compound; through the selective absorption and reflection of specific wavelengths of visible light. In physics and chemistry, the term is generally applied to the specific structural moiety that mediates the transition of electrons between energy states upon photon excitation. While historically associat…

   Rhodopsin and Vision
   The primary chromophore in vertebrate vision is 11-cis-retinal, an aldehyde derived from Vitamin A. When bound covalently to the opsin protein in the rod cells, this complex is known as rhodopsin. The absorption of a single photon by the chromophore causes an instantaneous isomerization of the 11-cis bond to an all-tra…
