Amino acids find their feet : Scanning tunneling microscopy of racemic ( R , S ) ‐ proline on Cu(110) reveals rows of random chiral amino acid sequences, showing that organization is not governed by molecular chirality. Instead, the system is dictated by a strict heterochiral adsorption‐footprint template, in which each adsorption position can be occupied by either enantiomer (see picture), resulting in a random solid solution in 2D.
