They have a trans acrylic acid at C-17 (ring D), instead of the propionic acid side chain of chlorophyll a and b, which in all polar chlorophyll c pigments is not esterified to phytol or other aliphatic long-chain alcohol. Initially, it was assumed that chlorophyll was a single compound but in 1864 Stokes showed by spectroscopy that chlorophyll was a mixture. Chlorophyll is a chelating ligand, which includes a central metal ion attached to the complex organic compound containing a mixture of carbon, nitrogen and hydrogen elements.
