Hemozoin structure
β-Hematin crystals are made of dimers of hematin molecules that are, in turn, joined together by hydrogen bonds to form larger structures. In these dimers, an iron-oxygen coordinate bond links the central iron of one hematin to the oxygen of the carboxylate side-chain of the adjacent hematin. These … Meer weergeven Haemozoin is a disposal product formed from the digestion of blood by some blood-feeding parasites. These hematophagous organisms such as malaria parasites (Plasmodium spp.), Rhodnius and Schistosoma Meer weergeven Black-brown pigment was observed by Johann Heinrich Meckel in 1847, in the blood and spleen of a person suffering from insanity.
