Description

General description

Protoporphyrin IX imparts red color to heme and is the major porphyrin in blood. It is synthesized from protoporphyrinogen IX in the presence of protoporphyrinogen IX oxidase.

Protoporphyrin IX belongs to the porphyrin family, which are a class of tetrapyrroles. It is the iron-free form of hemin and amphiphilic in nature. It is the precursor of heme in its biosynthetic pathway.

Application

Activates soluble guanylyl cyclase.

Protoporphyrin IX has been used:

• as a standard in protoporphyrin assays[1]
• in fluorescence spectra analysis
• to treat cells in cell culture to study heme-mediated ferroportin 1 transcription

Biochem/physiol Actions

Protoporphyrin IX levels are elevated in tumor cells due to metabolism anomalies compared to normal cells.

Protoporphyrin IX penetrates human erythrocytes and aids the release of oxygen from them. It forms complexes with myoglobin and hemoglobin. It is a photosensitizer used in the photodynamic therapy of cancer.
