1
Understand that human blood plasma contains various proteins, each with different functions and concentrations.
Recall that albumin is a protein primarily responsible for maintaining osmotic pressure and transporting various substances in the blood.
Recognize that transferrin is involved in iron transport, immunoglobulin G (IgG) functions in immune response, and fibrinogen plays a role in blood clotting.
Compare the typical concentrations of these proteins in plasma; albumin is known to be present at the highest concentration among them.
Conclude that the most abundant protein by concentration in human blood plasma is albumin.
