examples of plasma protein

albumin, globulin and fibrinogen

albumin

From d liver ●Most abundant (55-64%) ●4-5g/100mls of blood (3.5-5g/dl) ●D smallest size wit molecular weight of 69000- 70000 ●Total exchangeable albumin pool=4-5g/kg bodyweight ●38-45% intravascular ●10% of exchangeable pool degraded daily ●Replacement comes from hepatic cells producing 200 to 400mg/kg/day ●Synthesis decreases in fasting and increase in nephrosis because of loss in urine
