Albumin: maintains osmotic pressure, accounts for 60% of plasma proteins
Decreased albumin in liver damage (e.g., hepatitis, cirrhosis)
Globulins (alpha & beta): transport proteins for steroid hormones, trace minerals (e.g., ceruloplasmin for copper, transferrin for iron, retinol-binding protein for vitamin A)
Clotting Proteins: Factor 2, 7, 9, 10, protein C&S (vitamin K dependent), fibrinogen (factor 1)
Anti-clotting Proteins: Plasminogen (converted to plasmin), Antithrombin III (deactivates clotting factors)
