[BS] Q.9) Function of Plasma Proteins :

Ans.

(A) Albumin:

1. It maintains about 80% of Colloidal osmotic pressure of blood.
2. It maintains viscosity of blood.
3. It has Buffer action by virtue of H+ icon acceptance.
4. Determines sp. gravity of plasma which is 1.028
5. Acts as carrier protein for hormones, fatty acid, bilirubin, metal & drugs.

[B] Globulin:

1. a1 globulin transport of hormone such as Thyroxin, Cortisole etc.
2. a2 globulin transport Cu as Ceruloplasmin.
3. b globulin transport of Fe++ as transferin.
4. g from antibody and take part in immunity.
5. It maintains maintain about 20% Colloidal osmotic pressure.
6. Helps in buffer Action.
7. It maintenance of viscosity of blood.

[C] Fibrinogen:

1. It is a essential blood coagulating factor ( factor-1) so, helps blood coagulation.
2. It maintains viscosity of blood.
3. Helps in buffer action.

[D] Prothrombin:

1. It is a essential blood coagulating factor ( factor-2) so, helps blood coagulation.
