Chiral recognition using ions between photoexcited tryptophan and sugar in the gas phase
Enantiomer selectivity in cold gas-phase cluster ions of biological molecules as a model for chemical evolution in interstellar molecular clouds was investigated using mass spectrometry and UV spectroscopy. The chiral recognition mechanism between Trp and a monosaccharide changed depending on the photoexcitation wavelength: the enantiomer-selective reactions at 265–280 nm and change in the electronic structure of Trp at 280–290 nm.
