Chlorophyll-like

Chlorophyll is a porphyrin derivative conjugated with a magnesium ion that is found in plant chloroplasts, algae and cyanobacteria. Chlorophyll is essential to the process of photosynthesis. It absorbs light in the blue and red parts of the visible spectrum and transfers the absorbed photon energy to an electron, which is used to produce ATP. Several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants. Derivatives of chlorin by the presence of a fifth, ketone-containing ring beyond the four pyrrole-like rings. Pheophytin (phein) is aMg-free chlorophyll pigment
