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 ...

Some cofactors (including the iron-porphyrin prosthetic groups of hemoglobin and cytochromes) are synthesized de novo by humans and by other mammals, whereas others must be derived from diet and ...

The key to this success is a powerful iron-based catalyst, an iron porphyrin complex that resembles hemoglobin. Its advantage ...

In 1992, Takuzo Aida encapsulated a porphyrin at the center of a cavity consisting of a dendrimer molecule. A porphyrin is a dye-type molecule, like the iron porphyrin that binds molecular oxygen in ...
