Which proteins are dominant in the beta globulin region during electrophoresis?

The beta globulin region in protein electrophoresis is primarily characterized by the presence of specific proteins that play critical roles in various physiological processes. Transferrin and beta lipoprotein are indeed the dominant proteins found in this region.

Transferrin is an important protein involved in iron transport throughout the body. It binds iron in the bloodstream, ensuring proper iron metabolism and distribution. Beta lipoproteins, which include lipoproteins involved in lipid transport, are also constituents of the beta globulin fraction. These lipoproteins play a key role in the transport of cholesterol and triglycerides.

The other options present proteins that fall under different categories. For instance, albumin, which is found in the albumin region, plays a major role in maintaining oncotic pressure and transporting various substances in the blood. Alpha-1 antitrypsin is typically found in the alpha globulin region, where it functions primarily as a serine protease inhibitor. C1 esterase inhibitor and haptoglobin are also found in the alpha region due to their functions related to immune response and hemoglobin binding, respectively. Finally, fibrinogen and C-reactive protein are associated with coagulation and inflammation, sitting normally in the gamma or a separate section
