The liver
Most of the active functions of plasma membranes are carried out by proteins.
Diverse proteins embedded in the lipid bilayer or positioned at one of its surfaces carry out most of the membranes functions.
plasma membrane is made up of phospholipids,proteins and short carbohydrate chains.still the structure not visible.so there are several models which explains arrangement of these components.the most accepted is the fluid mosaic model

(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
Basically blood plasma minus proteins. The glomeruli can filter out most serum proteins, but lets a few small ones through (I think the cutoff is like 25kD). Some albumin does manage to get through, this is recovered in the proximal tubule.

Most coagulation are made in the liver.

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). (Fundamentals of Anatomy & Physiology, Martini, pages 640-642).
The single most abundant protein in normal plasma is albumin.
Albumin consist 60 percent of all plasma proteins. Therefore, they are the most abundant proteins.

A pancreatectomy is the most effective treatment for cancer of the pancreas, an abdominal organ that secretes digestive enzymes, insulin, and other hormones.
Function of the Pancreas The pancreas is a small organ located near the lower part of the stomach and the beginning of the small intestine. This organ has two main functions. It functions as an exocrine organ by producing digestive enzymes, and as an endocrine organ by producing hormones, with insulin being the most important hormone produced by the pancreas.The pancreas secretes its digestive enzymes, through a system of ducts into the digestive tract, while it secretes its variety of hormones directly into the bloodstream.Abnormal pancreatic function can lead to pancreatitis or diabetes mellitus.
