A magnesium atom is at the center of its porphyrin ring.
This molecule was studied by Theodor Engelmann, who used aerobic bacteria to determine its action spectrum. In diatoms, fucoxanthin masks the presence of this molecule, creating a golden color. A magnesium atom is at the center of its porphyrin ring. Special ones designated P680 and P700 are found in the reaction centers of photosystems. The two "c" forms are found in algae, while the "a" and "b" forms are used by plants. This pigment is located in the thylakoid membrane. For 10 points, name this pigment used in photosynthesis, which makes plants green.
