Blood proteins, also termed serum proteins or plasma proteins, are proteins found in blood plasma. They serve many different functions, including
- circulatory transport molecules for lipids hormones, vitamins and metals
- enzymes, complement components, protease inhibitors, and kinin precursors
- regulation 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.

What else can I help you with?
What are plasma proteins and their functions?
plasma proteins determine......
Does plasma membrane produce proteins?
No, the plasma membrane does not produce proteins. Proteins are synthesized by ribosomes in the cytoplasm and then transported to the plasma membrane to carry out various functions such as transport, signaling, and cell adhesion.
Does plasma contain proteins?
Yes. The major proteins found in plasma are fibrinogen, the protein that helps the blood to clot, antibodies, and enzymes.
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.
Plasma contains a much greater concentration of what than glomerular filtrate?
Proteins. Plasma contains a higher concentration of proteins compared to glomerular filtrate due to selective reabsorption of essential proteins by the kidney tubules.
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.
Does lympth or plasma have more proteins?
Plasma has much more proteins than lymph.

What are the proteins in plasma?
There are three types of proteins that are found in the plasma of blood. They are albumin, globulins, and fibrinogens.
What would a deficit of plasma proteins cause?

What is found in blood plasma but not in the fluid of the glomerular capsule?

Which drug is binding with plasma protein?
Many drugs bind with your plasma proteins or albumins. An example is Warfarin (Coumadin) which is 90% bound to plasma proteins.
Does plasma membrane produce proteins?
No, the plasma membrane does not produce proteins. Proteins are synthesized by ribosomes in the cytoplasm and then transported to the plasma membrane to carry out various functions such as transport, signaling, and cell adhesion.
Write the normal value of plasma protein?
Plasma proteins are proteins that are present in blood plasma. The normal laboratory value of plasma total protein is around 7 g/dL.
What plasma proteins helps maintain normal blood volume?
Which of the following plasma proteins help regulate blood volume?
What are other names for plasma?
plasma
What is the most abundant type of solute in the blood plasma is?
Plasma Proteins. Although Plasma is 92% water, that is the solvent in Plasma. Plasma proteins make up 7% of the whole Plasma volume as solutes. And other miniscule solvents make up the remaining 1%. Some Plasma proteins are Albumins, Globulins (Hormone-Binding Protein, Metalloproteins, Apolipoproteins, Steroid-Binding Proteins), Fribinogen, other varying Plasma Proteins and Peptide Hormones (Insulin, PRL, TSH, FSH, LH).
