BSA, Biotechnology grade, 100g.Bovine serum albumin (BSA) is a large globular protein (66,000 Dal) with a good essential amino acid profile . It has been well characterized and the physical properties of this protein are well known ( Peters, 1975). BSA binds free fatty acids, other lipids and flavor compounds, which can alter the heat denaturation of the protein (Kinsella and Whitehead, 1992). Isolated BSA has been reported to be a very functional protein (Waniska, et.al., 1981). It is reported to partially unfold between 40 and 50oC, exposing non-polar residues on the surface and facilitating reversible protein-protein interactions.
