Definition of Solvent Accessible Surface Area. The concept of the solvent accessible surface of a protein molecule was originally introduced by Lee and Richards (1971), as a way of quantifying hydrophobic burial. The solvent accessible area (ASA) describes the area over which contact between protein and solvent can occur. thai slips
