List the three major plasma proteins in plasma.

The main concept here is that plasma proteins fall into three broad, functionally distinct groups: albumins, globulins, and fibrinogen. Albumins are the most abundant proteins in plasma and are essential for maintaining colloid osmotic pressure, which helps keep fluid in the vessels; they also act as carriers for hormones, fatty acids, and other substances. Globulins comprise several classes, including transport proteins and antibodies (immunoglobulins), giving them roles in transport and immune defense. Fibrinogen is a soluble coagulation factor that, when activated by thrombin, is converted into fibrin to form a clot. Because these three categories capture the major functional roles and abundance of plasma proteins, they are the correct trio to list.
