What is another word for protohemin?
Pronunciation: [pɹˈə͡ʊtə͡ʊhˌɛmɪn] (IPA) 
Protohemin is a term that refers to heme biosynthesis, which is a naturally occurring organic molecule that is a crucial component of many proteins in the body. As a result, several synonyms can be used to describe protohemin, such as hemin, ferriprotoporphyrin IX, and porphyrin. Hemin is a porphyrin-containing iron molecule that is produced by the breakdown of hemoglobin in red blood cells. It is essential for oxygen transportation by binding to the oxygen in the lungs and then releasing it in the body's tissues. Ferriprotoporphyrin IX is also a hemic molecule, which contains a central iron ion surrounded by a porphyrin ligand. The term porphyrin refers to a family of organic compounds with ring structures that are similar to heme.
