EssentialPhotosynthesis
The primary photosynthetic pigment in plants, algae, and cyanobacteria. Contains a magnesium ion at the center of a porphyrin ring. Absorbs red and blue light, reflecting green — the reason most plants are green.
IUPAC: magnesium methyl (3R,21S,22S)-16-ethenyl-11-ethyl-12,17,21,26-tetramethyl-4-oxo-22-[3-oxo-3-[(E,7R,11R)-3,7,11,15-tetramethylhexadec-2-enoxy]propyl]-23,25-diaza-7,24-diazanidahexacyclo[18.2.1.15,8.110,13.115,18.02,6]hexacosa-1,5,8(26),9,11,13(25),14,16,18,20(23)-decaene-3-carboxylate
