Functions of the plasma proteins include :
  • Intravascular osmotic effect. This is important in maintaining fluid and electrolyte balance and is discussed more fully in those sessions.
  • Contributes to the viscosity of the plasma
  • Transport of insoluble substances around the body by allowing them to bind to protein molecules.
  • Protein reserve for the body
  • Clotting this is discussed further in sessions on wounds and wound healing
  • Inflammatory response again discussed further in the sessions on the immune system.
  • Protection from infection the gamma globulins function as antibodies and their role is discussed more fully in the sessions on the immune system.
  • Maintenance of the acid-base balance. Again this is explored in more detail in the session on fluid and electrolyte balance.
  • Blood plasma proteins like albumin functions as carrier proteins that help in the translocation of different biomolecules in body.
  • Blood plasma contains the protease inhibitor enzymes like alpha-1 antitrypsin that help in the reduced proteolytic activity in the blood.

The blood plasma contains inorganic ions which are important in regulating cell function and maintaining homeostasis.

The cell's plasma membrane does not simply form a "sack" in which to keep all the cytoplasm and other cellular organelles. The plasma membrane is a very important structure which functions to allow certain substances to enter or leave the cell. It can "pump" other substance into the cell against the concentration gradient or pump other "wastes" etc. out of the cell.

Some of the transport process happens "passively" without the cell needing to expend any energy to make them happen. These processes are called "passive transport processes".

Plasma help to regulate the body's osmotic pressure. It also transfers various compounds needed by the body. Also plays a role in the immune system and blood clotting. Plasma protein makes up 7% of the blood volume.

Plasma is a transport medium in the blood. Apart from red and white blood cells and platelets, it also transports soluble products of digestion (like glucose and amino acids). It takes oxygen and carbon dioxide to and from cells, which too dissolve in the plasma. Hormones are even transported to target organs from endocrine glands.

Plasma is the fluid part of the blood. It is a mixture of water, minerals, nutrients, sugars, proteins and other substances. Plasma also carries waste.

What would a deficit of plasma proteins likely cause?

If there is a decrease in the amount of plasma proteins, then overall health is affected. There are three main plasma proteins-albumins, globulins, and fibrinogen-that contribute to the composition of plasma. Osmotic pressure and the transport of fatty acids, thyroid hormones, some steroid hormones, and other substances will decrease. The amount of antibodies transported by the plasma will also decrease. Finally, the blood will not be able to clot properly because of the decrease of certain proteins in the plasma.


Do kidneys form plasma proteins?

Kidneys do not form plasma proteins. All plasma proteins, or blood proteins, are made in the liver, the one exception to this being gamma globulins.


What is the main purpose of proteins in the body?

There are innumerable functions of proteins in the body. Well, the primary functions of proteins include building and repairing of body tissues, regulation of body processes and formation of enzymes and hormones.
