Haems are the vital catalysts in a large number of biological processes, including oxygen transport, oxygen storage, electron transport and oxygenation. Haem proteins contain an iron complex of porphyrin, usually protoporphyrin IX, and exist in haemoglobin, myoglobin, cytochromes, catalases, peroxidases, oxygenases and oxidases.
