  • Chiroptical properties of amino acids are challenging to investigate in the gas phase due to the low vapor pressure of these molecules. Here the authors succeed in measuring circular dichroism active transitions and anisotropies in the ultraviolet range for several gas-phase amino acids, shedding light on the interactions between molecules and circularly polarized light that lead to chiral symmetry breaking.

  • Active regulation of chirality, or handedness, is crucial for life. Here, the authors describe assays to characterise proteome chirality in vivo and show that errors degrade enzyme activity triggering tumour formation and reduced lifespan.

  • Enantiomerically-enriched hydroxycarboxylic acids have been found in meteorites, but the possible origin of this asymmetry has not been explored experimentally. Here circular dichroism/anisotropy experiments suggest a common astrochemical mechanism for the generation of enantiomeric excess in hydroxycarboxylic acids and amino acids.
