Blood proteins
From Wikipedia, the free encyclopedia
(Redirected from Plasma protein)
Blood proteins, also called serum proteins, are proteins found in blood plasma. They serve as a transport molecule for lipids, hormones, vitamins and metals. They also serve as enzymes, complement components, protease inhibitors, and kininn precursors. Serum Proteins play an important role in the regulation of acellular activity and functioning and in the immune system. Separating serum proteins by electrophoresis is a valuable diagnostic tool as well as a way to monitor clinical progress.
Types of blood proteins:
alpha1-antiproteinase alpha2-macroglobulin
60% 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 35% of plasma proteins and are used in the transport of ions, hormones and lipids assisting in immune function. 4% is fibrinogen and this is essential in the clotting of blood and can be converted into insoluble fibrin. Finally regulatory proteins which make up less than 1% of plasma proteins are proteins such as enzymes, proenzymes and hormones.
