Porphyrins in health and disease

Porphyrins are components of Heme’s biosynthetic pathway. It is synthetized in the mitochondria of all living things’ cells. Heme controls oxygen in breath and detoxication but also promote the other gaz production like Nitric Oxide (NO), Hydrogen Sulfide (H2S) and Carbon Monoxide (CO) which are, all three of them, oxygen savers, antioxidants, anti-inflammatory agents and have a tissue protective effect.

Thus, Heme is a key component of oxygen homeostasis. The Porphyrin profile can be altered quantitatively by a rise of their synthesis level, qualitatively by a modification of their respective components proportions, or most of the time in both manners :

Role of porphyrins profile

To the extent that Heme’s biosynthetic pathway, sensitive to many toxics, is protected in the mainstay by an effective and multifaceted detoxication system, which is composed of Phase I CYP 450, Phase II transferases, peroxidases, epoxydases, dehydrogenases, including the ALDH (type II) ; a Porphyrin profile alteration can be regarded more broadely like an insufficient detoxication capacity of the metabolism regarding the stress it have to deal with.
