WebChlorophyll and bacteriochlorophyll are tetrapyrroles that are related to the parent structure of the cytochromes. But unlike cytochromes, chlorophylls contain magnesium instead of iron at the center of the ring. Chlorophylls also contain specific substitu- ents on the tetrapyrrole ring and a hydrophobic alcohol that helps anchor the ...
