Bacteriochlorophyll

Bacteriochlorophyll

Bacteriochlorophylls are photosynthetic pigments that occur in various phototrophic 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:

Bacteriochlorophylls "c", "d" and "e" are chlorins, with one reduced pyrrole ring (D), and the others are bacteriochlorins, with two (B and D).
