The different functions of plasma proteins are as follows:-
●ROLE IN COAGULATION OF BLOOD
●ROLE IN DEFENCE MECHANISM OF THE BODY
●ROLE IN MAINTAINING THE OSMOTIC PRESSURE IN THE BLOOD
●ROLE IN REGULATION OF ACID – BASE BALANCE
●ROLE IN VISCOSITY OF BLOOD
●ROLE IN ERYTHROCYTE SEDIMENTATION RATE
●ROLE IN SUSPENSION STABILITY OF RED BLOOD CELLS
●ROLE IN PRODUCTION OF TREPHONE SUBSTANCES
●ROLE AS RESERVE PROTEINS
●ROLE IN TRANSPORT MECHANISM
ROLE IN COAGULATION OF BLOOD:-
Fibrinogen is the substance which is essential for the coagulation of blood.
ROLE IN DEFENCE MECHANISM OF THE BODY:-
ϒ – Globulins also known as immunoglobulin acts as an antibody which plays an important role in the defense mechanism of the body.
ROLE IN TRANSPORT MECHANISM OF THE BODY
Plasma proteins are very much essential for the transport of various substances in the blood such as α and β-globulins help to transport metals in the blood
Albumin , α-globulin , β – globulin are very much essential for the transport of enzymes and hormones.
ROLE IN MAINTAINANCE OF OSMOTIC PRESSURE IN THE BLOOD
Plasma proteins exerts the colloidal osmotic pressure
Osmotic pressure exerted by the plasma protein is about 25mm hg.
Plasma protein exerts maximum osmotic pressure as the concentration of plasma protein is more than the other plasma proteins.
ROLE IN REGULATION OF ACID – BASE BALANCE
Plasma protein has an important role in the regulation of acid- base balance. It is due to the buffering action of albumin.
ROLE IN VISCOSITY OF BLOOD
Plasma proteins help in providing viscosity to the blood to maintain the blood pressure.
Here also albumin provides maximum viscosity than the other plasma proteins.
ROLE IN ERYTHROCYTE SEDIMENTATION RATE
Globulin and fibrinogen helps in accelerating the tendency of rouleax formation by the red blood cells
This Rouleax formation is responsible for erythrocyte sedimentation rate , which is an diagnostic and prognostic tool
ROLE IN SUSPENSION STABILITY OF RED BLOOD CELLS
At the time of circulation , red blood cells remains suspended uniformly in the blood. This is known as suspension stability.
Globulin and fibrinogen are the plasma proteins which helps in the suspension stability of the red blood cells.
ROLE IN PRODUCTION OF TREPHONE SUBSTANCES
Trephone substances are the substances which are produced by the leukocytes from the plasma proteins and are necessary for the nourishment of the tissue cells in the culture.
ROLE AS RESERVE PROTEINS
Plasma proteins are utilized by the body tissues as the last source of energy during fasting , inadequate food intake or inadequate protein intake.
By the help of tissue macrophages , plasma proteins split into aminoacids.
Amino acids returns to blood and gets distributed throughout the body to form cellular protein molecules.
Due to which plasma proteins are also known as the reserve proteins.
