Chemical Structure

Chlorophyll is a chlorin pigment, related to the porphyrin containing iron compound known as heme. At the center of the ring is a magnesium ion. The side chains vary somewhat between the different forms of chlorophyll found in different organisms - chlorophyll a is always present, but chlorophylls b and c also occur in various groups.
