Hemozoin formation is a process by which certain blood-feeding parasites, such as the malaria-causing Plasmodium species, detoxify free heme released during hemoglobin digestion by converting it into an inert crystalline form. This process is a target for antimalarial drugs, as disrupting hemozoin formation can lead to toxic buildup of free heme, ultimately killing the parasite.

Hemoglobin digestion is a process primarily occurring in blood-feeding parasites, like Plasmodium species, where hemoglobin from the host's red blood cells is broken down to release amino acids and heme. This process is crucial for the parasite's survival and growth, but also generates toxic heme, which the parasite detoxifies or sequesters to avoid damage.

Antimalarial drugs are medications designed to prevent and treat malaria, a life-threatening disease caused by Plasmodium parasites transmitted through the bites of infected Anopheles mosquitoes. These drugs work by interfering with the life cycle of the parasites, either by killing them or inhibiting their growth, and include several classes like quinolines, antifolates, and artemisinin derivatives, each with specific mechanisms of action and resistance profiles.
