Structural components of alginic acid. I. The crystalline structure of poly‐β‐D‐mannuronic acid. Results of X‐ray diffraction and polarized infrared studies
Abstract
A Structure determination of the naturally occuring marine algal polysaccharide poly‐β‐D‐mannuronic acid is described. The structure consists of 1e → 4e linked D‐mannuronic acid chains with the monosaccharide units in the C1 chair conformation. The X‐ray fiber diffraction photograph obtained from bundles of fibers prepared from Fucus vesiculosus has been indexed to an orthorhombic unit cell in which a =7.6 Å, b (fiber axis) = 10.4 Å, c = 8.6 Å, the unit cell containing two disaccharide chain segments with space group P2 1 2 1 2 1. A sheet‐like structure involving one intra‐chain, one intra‐sheet, and one inter‐sheet hydrogen bond per monosaccharide is proposed. Features of the chain‐packing arrangement are compared with mannan.

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.
