Plasma proteins account at least 8% of the plasma, they contribute to osmotic pressure and maintain water balance in blood and tissues, other functions includes transport and enzymatic activities. Plasma proteins include albumin, fibrinogen and globulin (alpha, beta and gamma). Globulin proteins may be used to fight infections such that gamma globulin antibodies are released by the plasma during immune response.
