Porphyrins are a group of chemical compounds of which many occur in nature, such as in green leaves and red blood cells, and in bio-inspired synthetic catalysts and devices. They are heterocyclic macrocycles characterised by the presence of one pyrroline and three pyrrole chemical groups interconnected via their α carbon atoms via methine bridges (=CH-). Porphyrins are aromatic, and they obey Hückel's rule for aromaticity in that they possess 4n+2 pi electrons that are delocalized over the macrocycle. The macrocycle, therefore, is a highly-conjugated system, and, as a consequence, is deeply colored - the name porphyrin comes from a Greek word for purple. The macrocycle has 26 pi electrons. The parent porphyrin is porphine, and substituted porphines are called porphyrins.
Therefore, it appears that you are gravely mistaken with the meaning of porphyrin.

What do plants use magnesium ions to make?
Magnesium is found in chlorophyll and this kind of pigment have a porphyrin ring associated with the protein.
Why do scientists use pigs blood to make photofrin?
Scientists use pig's blood to make Photofrin, a photosensitizing agent used in photodynamic therapy, because it contains a high concentration of the compound called porphyrin which is the active ingredient in Photofrin. Porphyrin is essential for the therapeutic effect of Photofrin as it produces reactive oxygen species when exposed to light, which selectively target and destroy cancer cells. Pigs have been found to have a higher yield of porphyrin in their blood compared to other animals, making it the preferred source for Photofrin production.
What are the 2 main parts of chlorophyll?
Chlorophyll consists of two main parts: the porphyrin ring and the phytol tail. The porphyrin ring contains a central magnesium ion and is responsible for absorbing light energy, primarily in the blue and red wavelengths. The phytol tail is a long hydrophobic chain that anchors chlorophyll to the thylakoid membranes of chloroplasts, allowing it to play a crucial role in photosynthesis. Together, these components enable chlorophyll to capture light energy and facilitate the conversion of carbon dioxide and water into glucose and oxygen.
Why is red blood cells are red in color?
Because they do not have a nucleus in order to have more space to carry oxygen. Also red blood cells have a life span of 120 days, after that period they die and are reabsorbed by the the liver.
Why are scientists interested in stem in stem cell research?
They hope to grow tissues to cure disease
Where is porphyrin of earthworm found?
Porphyrin of earthworm is found in the epidermis or the body wall.
When was Handbook of Porphyrin Science created?
Handbook of Porphyrin Science was created in 2010.
How many pages does Handbook of Porphyrin Science have?
Handbook of Porphyrin Science has 2000 pages.
What is the ISBN of Handbook of Porphyrin Science?
The ISBN of Handbook of Porphyrin Science is 978-981-4280-16-7.
Is there exists nickel porphyrin compounds?
Yes, nickel porphyrin compounds do exist. They are a class of organometallic compounds containing a central nickel atom coordinated to a porphyrin ligand. These compounds are commonly used as catalysts in a variety of chemical reactions.
What structural component does chlorophyll similar have that allows it to capture light?
porphyrin rings
Why do plants need magarine?
Plants need magnesium for making food !!!! Magnesium is the central atom in the porphyrin ring system in chlorophyll (the heme group in animals is also a porphyrin ring system, though there the central atom is iron).
What is heme biosynthesis?
Much of the heme biosynthesis pathway is dedicated to constructing the porphyrin molecule.
Why is hemoglobin only in the red blood cell?
The red colour is caused by a chemical known as a porphyrin which actually contains the iron atom in haemoglobin. The name porphyrin comes from the Greek for purple. There are lots of different kinds of haemoglobin depending on which species you belong to, but all have a similar structure of protein molecules and iron containing porphyrin molecules. Oh I forgot, the porphyrin molecule in haemoglobin is called ha em or heme, depends on where you come from. If you are interested some animals like octopus and squid have copper instead of iron in their oxygen carrying molecules.
What is an aminolysis?
An aminolysis is an amino derivative of levulinic acid, especially 5-aminolevulinic acid, intermediate in the biosynthesis of porphyrin.
