Plasma Proteins function

Plasma Proteins function

1. Albumin

   • Binds to Cu+II, Fatty acids, some drugs and minerals

2. Globulins

   • Bind to steroids, minerals, lipids, T3, T4 and some drugs.

3. Ceruplasmin

   • Transfer Cu+II

4. Transferrin

   • Iron ( Fe )

5. Lipoproteins

   • Carries TAGs

6. Thyroid binding globins

   • T3, T4

7. Fibrinogen & clotting factors

   • Coagulation process.
     • Anti-coagulation process, vitamin K dependant

8. Immunoglobulins

   • defense against micro-organisms

9. Proteins of inflammatory response

   • eg. C-reactive protein

10. Protein C & Protein S

11. Have role in maintaining blood volume through their osmotic pressure 25 mmHg carried out mainly by albumin.

12. Anti-protease activity

    • α1 antitrypsin
      • inhibits the enzyme "elastase" that damages lung tissues
    • Anti-thrombin III
      • when activated in the presence of heparin , it inhibits thrombin and other factors
