Glycan structures are often stabilized by a repertoire of hydrogen-bonded donor/acceptor groups, revealing longer-lived structures that could represent biologically relevant conformations. NMR provides unique data on these hydrogen-bonded networks from multidimensional experiments detecting cross-peaks resulting from through-bond (TOCSY) or through-space (NOESY) interactions. However, fast OH/H(2)O exchange, and the spectral proximity among these NMR resonances, hamper the use of glycans' labile...

[NMR paper] Automated glycan assembly of 19F labelled glycan probes enables high-throughput NMR studies of protein-glycan interactions
Automated glycan assembly of 19F labelled glycan probes enables high-throughput NMR studies of protein-glycan interactions
Protein-glycan interactions mediate important biological processes, including pathogen host invasion and cellular communication. Major challenges to monitoring these low affinity interactions are the required high sensitivity of a biophysical assay and to cover a breath of synthetic well-defined structures. Here, we showcase an expedite approach that integrates automated glycan assembly (AGA) of 19 F labelled probes and high-throughput NMR methods, enabling the study...

[Question from NMRWiki Q&A forum] OH, NH, SH Labile protons in water nmr
OH, NH, SH Labile protons in water nmr
Hello all,
Just to mirror Craig Grimmer's question about labile protons in non-aqueous solvents, does anyone know of any good articles dealing with labile proton behavior in water?
Thanks,
