Which protein is NOT a beta-globulin?

Explanation:
Beta-globulins are a group of serum proteins that migrate in the beta region on electrophoresis and include transferrin, C3 complement, and beta-2 microglobulin. Albumin sits in its own albumin fraction and is not a globulin. So the protein that is not a beta-globulin is albumin. Albumin helps maintain oncotic pressure and transports many substances, while transferrin carries iron, C3 is part of the immune complement system, and beta-2 microglobulin is associated with MHC class I molecules.
