<prompt> Most important function of albumin in body isOncotic pressureDrug transportToxic transportCoagulation  <response>: Osmotic pressure is determined by the number of molecules dissolved in a fluid rather than by the mass of these molecules. Therefore, when corrected for number of molecules rather than mass, the following chart gives both the relative mass concentrations gdl of the different types of proteins in normal plasma and their respective contributions to the total plasma colloid osmotic pressure Πp.
