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

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 ...

A research team led by Dr. Huang Qing from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has ...

Porphyrins are necessary for hemoglobin to function. This protein, found in the red blood cells, is responsible for carrying ...

A porphyrin is a dye-type molecule, like the iron porphyrin that binds molecular oxygen in the heme protein of red blood cells, or the chlorophyll that promotes photosynthesis in green plant cells. In ...

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 ...
