Many enzymes rely on iron porphyrin 'haem' centres to carry out important tasks in biology, in particular using their ability to bind small molecules such as O 2 and water.For example, the ...

Actually, porphyrin derivatives are an essential part of the respiratory enzymes present in all living cells, and an understanding of their nature and relations may be expected to lead to ...

This condition arises from a deficiency in the enzyme uroporphyrinogen III synthase (UROS), leading to the accumulation of toxic porphyrins in the body. The symptoms of CEP can be severe and ...

Furthermore, porphyrins are biological molecules, ubiquitous in nature (blood, plant leaves, enzymes, etc.). An intriguing feature of porphyrins is that their properties strongly depend not only ...
