Non‐degradative dissolution and acetylation of ball‐milled plant cell walls: high‐resolution solution‐state NMR
Open accessAbstract
Summary: Two solvent systems for fully dissolving, and optionally derivatizing, finely ground plant cell wall material at room temperature are described: dimethylsulfoxide (DMSO) and tetrabutylammonium fluoride (TBAF) or N‐methylimidazole (NMI). In situ acetylation produces acetylated cell walls (Ac‐CWs) that are fully soluble in chloroform. Lignin structures tested remain fully intact. The dispersion of 13 C–1 H correlations afforded by two‐dimensional (2D) nuclear magnetic resonance (NMR) experiments reveals the major lignin units, allowing the whole lignin fraction to be analyzed by high‐resolution solution‐state NMR methods for the first time. Non‐degradative cell wall dissolution offers the potential to analyze polysaccharide components, and improve current cell wall analytical methods by using standard homogeneous solution‐state chemistry.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
