$i A group of compounds containing the porphin structure, four pyrrole rings connected by methine bridges in a cyclic configuration to which a variety of side chains are attached. The nature of the side chain is indicated by a prefix, as uroporphyrin, hematoporphyrin, etc. The porphyrins, in combination with iron, form the heme component in biologically significant compounds such as hemoglobin and myoglobin. $2 eng 680 $a pigments; iron porphyrins = HEME or HEMIN, magnesium porphyrins = CHLOROPHYLL $2 eng 750 -2
