There are numerous kinds of proteins in the blood, thus proteins have many important functions. The major ones are:
Other functions exist, though.
Plasma proteins perform various functions. Plasma contains hundreds of proteins each having their specific function. A major protein is Albumin, which is responsible for transport of fatty acids, lipids, drugs etc in the body, it also maintains the osmotic balance with body. Albumin is followed by Immunoglobulins, which are responsible for the immune response. Fibrinogen is responsible for the blood clotting at the time of injury. There is a long list of proteins and an even longer list of their functions.
it does not start the clotting process. platelets start the cloting process.
No, clotting is not a major function of the plasma proteins in the blood. This particular function is carried out by platelets
fibrinogen
Yes. The major proteins found in plasma are fibrinogen, the protein that helps the blood to clot, antibodies, and enzymes.
Plasma is one of the major parts of the blood. It is the liquid that is left after the other major parts, like red blood cells and white blood cells, are removed. It contains many different essential proteins, as well as salts and sugars.
Buffering in the blood is by the carbonic acid - hydrogen carbonate buffer. (Hydrogen carbonate is also called by the older name "bicarbonate"). The plasma pH is maintained at about 7.4. Functions of blood proteins: serum albumin: binds to certain molecules to help transport them in the bloodstream; contributes to the osmotic pressure of the plasma to the extent of 80% serum globulins: are antibodies, contributes to the osmotic pressure of plasma to the extent of 20% serum fibrinogen:antibodies serum prothrombin: blood clotting factor
The major plasma proteins are Albumin ,Globulins, and Fibrinogen. Clotting factors also are plasma proteins.
Albumin=exertion of osmotic pressure. Globulins=immunity. Fibrinogen=hemostasis and viscosity.
Serum Proteins.
Serum albumin accounts for 55-60% of blood proteins, and is a major contributor to maintaining osmotic pressure.

(November 2012)Blood proteins, also termed serum proteins or plasma proteins, are proteins found in blood plasma. They serve many different functions, includingcirculatory transport molecules for lipids hormones, vitamins and metalsenzymes, complement components, protease inhibitors, and kinin precursorsregulation of acellular activity and functioning and in the immune system.The normal laboratory value of serum total protein is around 7 g/dL.Separating serum proteins by electrophoresis is a valuable diagnostic tool as well as a way to monitor clinical progress.Contrary to popular belief, hemoglobin is not a serum protein. It is contained within the red blood cells, rather than in the blood serum.All the plasma proteins are synthesized in liver except for the gamma globulins.55% of plasma proteins are made up of the protein albumin, which are major contributors to osmotic pressure of plasma which assists in the transport of lipids and steroid hormones. Globulins make up 38% of plasma proteins and are used in the transport of ions, hormones and lipids assisting in immune function. 7% is fibrinogen which is essential in the clotting of blood and can be converted into insoluble fibrin. Regulatory proteins which make up less than 1% of plasma proteins are proteins such as enzymes, proenzymes and hormones. Current research regarding blood plasma proteins is centered on performing proteomics analyses of serum/plasma in the search for biomarkers. These efforts started with two-dimensional gel electrophoresis[1]efforts in the 1970s and in more recent times this research has been performed using LC-tandem MS[2][3]based proteomics.[edit]Families of blood proteinsBlood protein Normal level % Function Albumins 3.5-5.0 g/dl 55% create oncotic pressure and transport insoluble molecules Globulins 1.0-1.5 g/dl 38% participate in immune system Fibrinogen 0.2-0.45 g/dl 7% Blood coagulation Regulatory proteins
the complement system includes about 20 plasma proteins that normally circulate in the blood. the complement system provides major protection for our body.

Plasma is a major component of animal blood. Someone can find plasma in the blood of mammals such as goats or cows. It is important to note that plasma from one animal varies greatly from that of a different animal.
