👉 The term "haematine" refers to a type of protein found in blood cells, specifically red blood cells. These proteins are responsible for carrying oxygen-rich hemoglobin molecules throughout the body, transporting oxygen from the lungs to tissues and organs. The presence of haematine is often seen in individuals with sickle cell disease, which is characterized by the presence of a genetic mutation that causes the production of abnormal hemoglobin or haemocytins.
