Evolution of the ratio between the atomic hydrophilicity and the total molecular surface area (hydrophilic <i>relative</i> density); and of the ratio between the atomic and the amino acid hydrophilicity relative densities; vs. probe dimensions for 5 model proteins: lysozyme (1LYZ); ribonuclease-A (1AFU); human hemoglobin (1Y4F); human serum albumin (1AO6); human IgG (1HZH).
