Name the major classes of plasma proteins and describe their functions.

Answer»

Three major classes of plasma proteins are : 

  1. Serum albumin, 
  2. Serum globulin, 
  3. Fibrinogen. 

Functions of plasma proteins: 

(i) Body immunity : Globulin is associated with the immune response and act as antibodies. 

(ii) Prevention of blood loss : Fibrinogen which is formed in the liver is necessary for the clotting (coagulation of blood). 

(iii) Retention of fluid in the blood : Albumin and globulin retains water in blood plasma. Deficiency of protein leads to loss of water from blood to tissue. That's why hands and feet gets swollen (edema).
