Photopigments are unstable pigments that undergo a chemical change when they absorb light. The term is generally applied to the non-protein chromophore moiety of photosensitive chromoproteins, such as the pigments involved in photosynthesis and photoreception. In medical terminology, "photopigment" … See more Photosynthetic pigments convert light into biochemical energy. Examples for photosynthetic pigments are chlorophyll, carotenoids and phycobilins. These pigments enter a high-energy state upon absorbing a photon … See more • Biological pigment See more The pigments in photoreceptor proteins either change their conformation or undergo photoreduction when they absorb a photon. This change in the … See more In medical terminology, the term photopigment is applied to opsin-type photoreceptor proteins, specifically rhodopsin and photopsins, the photoreceptor … See more WebPhotopigments are G-protein-coupled transmembrane proteins contained within the Photoreceptors.
