Porphyrins (from the Greek for "purple") are a group of organic molecules that share the characteristic of having four pyrolle subunits (made up of C4H4NH groups) connected with methine bridges (=CH-) at the carbon atoms. Heme is the best known of the porphyrins. Porphyrins also are the basic building block of chlorophyll in plants.
