TLDR
A new three-dimensional structure of the crystalline part of A-starch is described in which the unit cell contains 12 glucose residues located in two left-handed, parallel-stranded double helices packed in a parallel fashion; four water molecules are located between these helices.About:

Preparation of Amylose-Carboxymethyl Cellulose Conjugated Supramolecular Networks by Phosphorylase-Catalyzed Enzymatic Polymerization
TL;DR: In this paper, the authors reported the preparation of amylose-carboxymethyl cellulose (CMC) conjugated supramolecular networks, by the phosphorylase-catalyzed enzymatic polymerization, using maltoheptaose primer-grafted CMC.

X-Ray Scattering and Diffraction
TL;DR: The contribution of X-ray diffraction to conventional structural chemistry has been large as mentioned in this paper, especially through its application to single crystals, and much of our information about molecular geometry has come from this source.

Characterization of native and plasticized starch using solid state NMR
TL;DR: In this article, the phase composition of starch-based materials can be determined by the decomposition of its 13C NMR spectrum into the sub-spectra of the ordered (crystalline and interfacial) and amorphous phases.

Relationship between the distribution of the chain length of amylopectin and the crystalline structure of starch granules
TL;DR: The distribution of chain lengths in the amylopectins of starches from 20 species (11 A-, 6 B-, and 3 C-type) were characterised by h.p.l.c. as mentioned in this paper.
Journal ArticleDOI
The double-helical molecular structure of crystalline b-amylose☆
TL;DR: The crystal structure of A-amylose is based on parallel-stranded, right-handed double helices as mentioned in this paper, which results in nearly hexagonal close-packing, and the similarities in packing suggest that interconversions of A and B are possible.

Molecular organization in starches: a carbon 13 CP/MAS NMR study
TL;DR: In this article, the authors used cross polarization/magic angle spinning (CP/MAS) 13C NMR spectra for starches from various botanical origins and analyzed by comparison with model materials.

Method for Calculating Internal Rotation Barriers

TL;DR: It was found that U0 was essentially constant within each class, thus allowing these average values to be used to calculate ΔU for all molecules in each class and satisfying agreement between the calculated values and experimental values of ΔU was found.
