👉 Antihemoglobin is a protein that helps to bind with and prevent the formation of hemoglobin in red blood cells. Hemoglobin, also known as oxygen-carrying protein, carries oxygen from the lungs to the rest of the body. It's essential for providing energy and carrying nutrients to all parts of the body. When the amount of hemoglobin in the body is reduced or absent, it can lead to a condition called anemia.
