👉 The term "antihemolysin" is a scientific term used to describe a protein that acts as an inhibitor of red blood cells. Red blood cells, or erythrocytes, are responsible for carrying oxygen and carbon dioxide throughout the body. They are made up of hemoglobin and myeloglobin, two different proteins that bind to iron in the bloodstream. The function of an antihemolysin is to prevent the formation of red blood cells that contain too much iron.
