Freeze-fracture preparation of P.falciparum hemozoin Fri, 24 November 2006 03:14: Hemozoin crystals exhibit a triclinic habit (Parasitol Res 100, 2007, 671-676).

Hemozoin is a disposal product formed from the digestion of blood by some blood-feeding parasites. Haematophagous organisms such as Malaria parasites (Plasmodium spp.), Rhodnius ...

To avoid destruction by this molecule, the parasite biocrystallizes heme to form hemozoin, a non-toxic molecule. Hemozoin collects in the digestive vacuole as insoluble crystals.
