Hemin is a metal porphyrin compound, composed of a molecule of ferrous iron and protoporphyrin complex, and is an in vitro group substitute of heme.
Hemin has a high iron content and a stable molecular structure. It is involved in the production of hemoglobin, and its absorption rate is better than traditional iron supplements and it has a good iron supplement effect.
Hemin powder has the appearance of blue-black crystals, is odorless and tasteless, and is insoluble in water and acetic acid.
Its chemical properties are similar to heme.
