Plasma Proteins

globulins

36% of plasma proteins

fibrinogen

4% of plasma proteins, produced by liver, forms fibrin threads of blood clot

albumin

60% of plasma proteins, produced by liver, main contributor to osmotic pressure

gamma

antibodies released by plasma cells during immune response

nonprotein nitrogenous substances

by products of cellular metabolism, such as uric acid

enzymes

carry on metabolic functions

electrolytes

cations include sodium, potassium, calcium, magnesium, anions include chloride, phosphate, sulfate and bicarbonate, help to maintain plasma osmotic pressure and normal blood pH

nutrients

materials absorbs from digestive tract and transported for use throughout body, include glucose and other simple carbohydrates, amino acids fatty acids, glycerol and triglycerides, cholesterol and vitamins

respiratory gases

oxygen and carbon diaoxide, oxygen mostly bound to hemoglobin inside RBCs, carbon dioxide transported disolved in plasma as bicarbonate ion or CO2, or bound to hemoglobin in RBCs.

alpha and beta globulins

produced by liver, most are transport proteins that bind to lipids, metal ions and fat soluble vitamins

hormones

steriod and thyroid hormones carried by plasma proteins
