Analysis of the aromatic amino acids phenylalanine, tyrosine, histidine, and tryptophan indicates that dimers of these side chains have many possible stabilizing interactions at distances larger than the average van der Waals radii.
Analiza aromatičnih aminokiselina fenilalanina, tirozina, histidina, i triptofana indiciraju da dimeri tih bočnih lanaca imaju mnoštvo mogućih stabilizujućih interakcija na rastojanjima većim od prosečnih van der Valsovih radijusa.
