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
