A schematic diagram of a molecule and its beta-shape. Figure drawn by using the BetaConcept[44] and BetaMol program freely available from VDRC.

(a) A two-dimensional molecule, (b) A two-dimensional molecule and its Connolly surface corresponding to the red circular probe, and (c) the beta-shape corresponding to the probe, (d) the van der Waals model of a protein (PDB id 1oq5), (e) the Connolly surface for water molecule (with 1.4Å radius), and (f) the corresponding beta-shape.
