All but one protein are components of the BETA-GLOBULINS. Which one is not?

Beta-globulins are a category of globulins that play various roles in transport, immune response, and metal ion binding. Ceruloplasmin, while it is an important copper-carrying protein in the blood, is classified as an alpha-2 globulin rather than a beta-globulin.

Transferrin, hemopexin, and complement components are all categorized within the beta-globulins. Transferrin is primarily responsible for iron transport, hemopexin binds free heme, and complement components are integral to the immune system’s function.

This distinction is critical in clinical chemistry, as it allows for accurate identification and classification of proteins based on their characteristics and roles in the body, aiding in diagnostic processes, treatments, and understanding various diseases.
