Globin is a type of protein that plays a crucial role in the transport of oxygen in the body. It is a component of hemoglobin, the protein found in red blood cells that carries oxygen from the lungs to tissues and organs. Globin proteins can be classified into different types, including alpha and beta globins, which combine to form hemoglobin. In addition to hemoglobin, globin proteins are also found in other forms, such as myoglobin, which is present in muscle tissues. Myoglobin helps store oxygen in muscles, providing energy during physical activity. Both globin types are essential for maintaining proper oxygen levels in the body.
