Abstract: The major factor that drives a protein toward collapse and folding is the hydrophobic e ect. At the folding process a hydrophobic core is shielded by the solvent-accessible surface area of the protein. We study the behavior of the numbers in 5526 protein structures present in the Brookhaven Protein Data Bank. The rst digit of mass, volume, average radius and solvent-accessible surface area are measured independently and we observe that most of these geometric observables obey the Newcomb{Benford law. That is volume, mass and average radius obey the Newcomb{Benford law. Nevertheless, the digits of the solvent-accessible surface area do not agree with the Newcomb{Benford law. The present ndings indicate that the hydrophobic e ect is responsible for the anomalous rst digit behavior of solvent-accessible surface areas.
