Chiral and molecular recognition between tryptophan (Trp) and monosaccharides in the gas phase was investigated as a model for chemical evolution in interstellar molecular clouds. UV photodissociation spectra and product ion spectra of cold gas-phase hydrogen-bonded clusters of protonated Trp and monosaccharides were obtained using a tandem mass spectrometer equipped with an electrospray ionization source and a cold ion trap. The spectra showed that the geometric and electronic structures of Trp achieve molecular recognition via hydrogen bonding.
