ABSTRACT
A group of porphyrin compounds is one of the most precious groups of molecules for life. Porphyrins and their metal complexes are found in every tissue of an organism [1]. Chlorophyll has a key role in photosynthesis [2,3]. Iron porphyrin in heme is essential to the molecular oxygen transport by hemoglobin in blood and myoglobin in muscular systems [4]. Electron transport in the respiration cycle is governed by porphyrins in cytochrome. P-450 is a crucial enzyme in metabolic processes.
