beta globulin

Beta globulin is a type of protein found in blood serum. Blood serum contains approximately 7% protein, with albumin making up two-thirds and globulins the remaining third. Globulins are further categorized into alpha-, beta-, and gamma-globulins, each representing a mixture of different proteins. Beta-globulins, specifically, include lipoproteins, mucoproteins, and metal-binding proteins like transferrin and ceruloplasmin, which are responsible for carrying iron and copper in the blood. Hemoglobin, the protein in red blood cells that transports oxygen, is composed of heme groups and a globin group, and variants like hemoglobin S are associated with conditions such as sickle cell anemia.123
