Forms of iodopsin
WebBoth rods and cones contain light sensitive pigments known as rhodopsins. Each rhodopsin molecule consists of a large protein, opsin, which behaves as an enzyme, and a small carotenoid molecule, retinal, a derivative of vitamin A. When a quantum of light strikes the photo pigment and is absorbed by the rhodopsin molecule, retinal is isomerized ... WebBy far the most abundant cone pigment in every bird species examined is the long-wavelength form of iodopsin, which absorbs at wavelengths near 570 nm. This is roughly the spectral region occupied by the red- and …
