Blood Plasma Plasma- transparent, yellow liquid vehicle for cells Serum- plasma without fibrinogen Serum Proteins: Albumin (@ 60 K) - colloid osmotic pressure and provide for solubility of hydrophobic components (e.i. lipids) Globulins (> 80 K) gamma globulins- e.i. IgG (immune globulins-antibodies) beta globulins - hormone transport (e.i. thyrogloblin) Transferrin- iron transport Cerruloplasmin- copper transport Serum Lipoproteins chylomicrons- fatty acid transport Very Low Density Lipoproteins (VLDL)) Low Density Lipoproteins (LDL) High Density Lipoproteins (HDL)
