Bacteriochlorophylls are photosynthetic pigments that occur in various bacteria. They are related to chlorophylls, which are the primary pigments in plants, algae, and cyanobacteria. Groups that contain bacteriochlorophyll conduct photosynthesis, but do not produce oxygen. They use wavelengths of light not absorbed by plants. Different groups contain different types of bacteriochlorophyll: ...more on Wikipedia about "Bacteriochlorophyll"
Bacteriorhodopsin is the photosynthetic pigment used by archaea, most notably halobacteria. It acts as a proton pump, i.e. it captures light energy and uses it to move protons across the membrane out of the cell. The resulting proton gradient is subsequently converted into chemical energy. ...more on Wikipedia about "Bacteriorhodopsin"
Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Its name is derived from ancient Greek: chloros = green and phyllon = leaf. Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color. ...more on Wikipedia about "Chlorophyll"
Phaeophytin is a grey pigment that appears in chromatograms of photosynthetic pigments. ...more on Wikipedia about "Phaeophytin"
A photosynthetic pigment is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis. ...more on Wikipedia about "Photosynthetic pigment"
Phycobilins are photosynthetic pigments found in cyanobacteria and in the chloroplasts of red algae, glaucophytes and some cryptomonads (though not in green algae and higher plants). They are unique among the photosynthetic pigments in that they are bonded to certain water-soluble proteins, known as phycobiliproteins; phycobilins serve as chromophores (the light-capturing part) of the phycobiliproteins. Phycobiliproteins capture light energy which is then passed on to chlorophylls during photosynthesis. ...more on Wikipedia about "Phycobilin"
Phycoerythrin is a red protein from the light-harvesting phycobiliprotein family, isolated from red, blue-green, and cryptomonad algae. ...more on Wikipedia about "Phycoerythrin"
Proteorhodopsin is a photoactive protein in marine bacterioplanktons. Just like the homologous pigment bacteriorhodopsin found in some archaea, it consists of a transmembrane protein bound to a retinal molecule and functions as a light-driven proton pump. Some members of the family (of more than 800 types) are beleived to have sensory functions. ...more on Wikipedia about "Proteorhodopsin"
