Core metal of chlorophyll is Mg.
Chlorophyll is any of several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants.
The presence of magnesium in chlorophyll was discovered in 1906, and was that element's first detection in living tissue. A molecular formula of C₅₅H₇₀O₆N₄Mg and a structure of (2-formyl)-chlorophyll were deduced based on NMR.
