Containing a magnesium in a porphyrin, it absorbs light maximally at 680 and 700 nm wavelengths.
Its heterocyclic polyene structure allows for high molar extinction coefficients. Energy is passed to it by exciton transfer from antenna molecules next to its position in a reaction center. A carboxyl substituent esterified to a phytol chain makes up ring IV of this molecule, whose a and b forms differ by a methyl vs. formyl group in ring II. Containing a magnesium in a porphyrin, it absorbs light maximally at 680 and 700 nm wavelengths. FTP name this green pigment of photosynthesis.
