- 3 August 2018 (modifié le 25 March 2020)In contrast, very strong chirality dependence of the structure is observed for cyclo tyrosine-tyrosine, cyclo Tyr-Tyr. While both LL and LD diastereomers show the same “folded extended” structure as cyclo Phe-Phe, a structure involving a strong hydrogen bond between the hydroxyls of the two tyrosine residues is observed for LL only.
