Serum albumin is the main protein of plasma and has a good binding capacity for water, Ca2+, Na+, K+, fatty acids, hormones, pharmaceutical molecules and more. Bovine serum albumin (BSA) is a globular protein that is used in numerous biochemical applications due to its stability and lack of interference with biological reactions. Its main function is the regulation of the colloidal osmotic pressure of blood, it is also a major zinc transporter in plasma. Serum also binds to many other water-insoluble molecules. Serum has a particular affinity for many drug molecules, such as ibuprofin, and can strongly affect the way they are delivered through the body.
