NMR spectroscopy in the structural elucidation of oligosaccharides and glycosides.
TLDR
The potential of one- and two-dimensional NMR techniques for the identification of individual sugar residues, their anomeric configuration, interglycosidic linkages, sequencing and the site of any appended group in establishing the structures of naturally occurring oligosaccharides and glycosides is presented.About:

Proteoglycans and Related Components in Plant Cells
TL;DR: Although functions of arabinogalactan proteins have not been clearly identified, regulated expression and several other lines of evidence point to involvement in plant reproductive development, pattern formation, and somatic embryogenesis, as well as in the underlying processes of cell division, cell expansion, and cell death.

FT-IR spectra of alginic acid block fractions in three species of brown seaweeds.
TL;DR: Two-dimensional spectra were collected to confirm the fine structure of the hetero- and homopolymeric fractions, and good agreement was obtained between its corresponding calculated vibrations and the experimental bands assigned to homopolyguluronic acid blocks.
Journal ArticleDOI
Isolation and characterization of novel benzoates, cinnamates, flavonoids, and lignans from Riesling wine and screening for antioxidant activity.
TL;DR: A German Riesling wine has been fractionated with the aid of countercurrent chromatography and the structures of 101 compounds were established by mass spectrometry and NMR spectroscopy, finding forty-four compounds exhibited a phenolic or benzylic structure.

TL;DR: In this article, the detection of NMR spectra of less sensitive nuclei coupled to protons was improved by a 2-dimensional Fourier transform technique involving a double transfer of polarization.

Improved spectral resolution in cosy 1H NMR spectra of proteins via double quantum filtering.
TL;DR: The elimination of the dispersive character of the diagonal peaks in phase-sensitive, double quantum-filtered COSY spectra allows identification of cross peaks lying immediately adjacent to the diagonal, which represents a significant improvement over the conventional COSy experiment.
