text: The following is a list of structural features that can be elucidated by NMR:
  * Chemical structure of each carbohydrate residue in a molecule, including
  ** carbon skeleton size and sugar type (aldose/ketose)
  ** cycle size (pyranose/furanose/linear)
  ** stereo configuration of all carbons (monosaccharide identification)
  ** stereo configuration of anomeric carbon (α/β)
  ** absolute configuration (D/L)
  ** location of amino-, carboxy-, deoxy- and other functions
  * Chemical structure of non-carbohydrate residues in molecule (amino acids, fatty acids, alcohols, organic aglycons etc.)
  * Substitution positions in residues
  * Sequence of residues
  * Stoichiometry of terminal residues and side chains
  * Location of phosphate and sulfate diester bonds
  * Polymerization degree and frame positioning (for polysaccharides)
