Biochem/physiol Actions

Bovine serum albumin (BSA) has been used as a model protein in various studies, such as immunodiagnostic procedures, cell culture media and clinical chemistry and relevant in foods containing bovine milk or meat. Serum albumins play a dominant role in drug disposition and efficacy by maintaining osmotic blood pressure.

General description

Bovine serum albumin (BSA) is a single polypeptide chain consisting of about 583 amino acid residues and no carbohydrates. It is a 66.4kDa, water-soluble protein. BSA is characterized with three homologous domains formed by six α-helices. Depending on pH, it undergoes reversible conformational isomerization. The native structure of the protein becomes reactive and flexible on heating.
