TLDR
It was verified that the pyranose ring exists in the 1C (1-C4) conformation as the alph-D anomer and no mutarotation was detectable and coupling constants for the glycerol side chain were interpreted to yield its most likely conformation.About:

TL;DR: It is demonstrated that deriving dihedral parameters by fitting to QM data for internal rotational energy curves for representative small molecules generally leads to correct rotamer populations in molecular dynamics simulations, and that this approach removes the need for phase corrections in the dihedral terms.

Prediction of anti and gauche vicinal proton‐proton coupling constants in carbohydrates: A simple additivity rule for pyranose rings
TL;DR: In this article, a set of parameters were used to calculate 3J(HH) coupling constants in a variety of pyranosides and related compounds and a comparison with experimental values taken from the literature showed that couplings in molecules which are conformationally pure and underformed can be predicted with a surprising accuracy.

3-deoxy-d-manno-2-octulosonic acid (KDO) is a component of rhamnogalacturonan II, a pectic polysaccharide in the primary cell walls of plants
TL;DR: Improved methods for detecting and quantitating KDO residues in polysaccharides were developed during this investigation and KDO was shown to be present in purified cell walls of several plants, including dicots, a monocot, and a gymnosperm.

Contact Electron‐Spin Coupling of Nuclear Magnetic Moments
TL;DR: In this article, the valence-bond theory for the contact electron-spin coupling of nuclear magnetic moments is used to calculate the proton−proton, proton-fluorine, and fluorine-florine coupling constants in ethanic and ethylenic molecules.

TL;DR: It is concluded that the major, alkali-labile oligosaccharide of sialoglycopeptides is a tetrasaccharides and that other components are degradation products thereof.
