Albumin2. Globulins3. Fibrogens(all 3 proteins determine osmolarity & osmotic pressure)Albumin:Makes up 60% of plasma proteinsFunction:-transporter for (fatty acids, hormones, ions, nutrients)-buffers pH-contributes to blood viscosityHas GREATEST impact in determining:-osmolarity-osmotic pressureGlobulins:Makes up 36% of plasma proteinsIncludes:-Lipoproteins-Complement proteins-Antibodies-Other functional
