We report a combination of laser spectroscopy in molecular jets and quantum mechanical calculations to characterize the aggregation preferences of phenyl-β-D-glucopyranoside (β-PhGlc) and phenyl-β-D-galactopyranoside (β-PhGal) homodimers. At leas

We studied N 1s−1 inner-shell processes of the free base Phthalocyanine molecule, H2Pc, in the gas-phase. This complex organic molecule contains three different nitrogen sites defined by their covalent bonds. We identify the contribution of each si

N-glycosylation of eukaryotic proteins is widespread and vital to survival. The pentasaccharide unit −Man3GlcNAc2– lies at the protein-junction core of all oligosaccharides attached to asparagine side chains during this process. Although its abso
