NMR characterization of chemically synthesized branched α-dextrin model compounds

- Chemical shifts were accurately determined for chemically synthesized branched α-glucans.
- The model compounds range from isomaltose to a doubly branched decasaccharide.
- gauche-trans populations of the C5-C6 bond correlate with the 13C6 chemical shift.
- The model compounds facilitate the identification of starch fragments in mixtures.
