Conformation and intermolecular interactions of carbohydrate chains

Journal of Supramolecular Structure, 1977
AbstractFor consideration of their conformations and interactions, carbohydrate chains can conveniently be divided into 3 classes on the basis of their covalent structure; namely periodic (a), interrupted periodic (b), and aperiodic (c) types. In aqueous solution carbohydrate chains often exist as highly disordered random coils.

Conformational restriction by intramolecular hydrogen bonding. Carbohydrate-carbohydrate self-assembly

Tetrahedron Letters, 1997
Abstract NMR data (chemical shifts, NOEs, coupling constants and variable temperature experiments), FT-IR data and MM2 ∗ molecular mechanics calculations have allowed us to demonstrate that 3-amido-1,6-anhydro-3-deoxy-β-D-glucopyranose acts as a hydroxyl-based interaction unit and provides conformational control of self-recognition processes by ...

Optical activity and conformation of carbohydrates

Carbohydrate Research, 1971
Abstract The methyl 2-acetamido-2-deoxy-α- and β- D -mannopyranosides and their corresponding furanosides have been prepared by treatment of 2-acetamido-2-deoxy- D -mannose with methanol in the presence of Amberlite IR-120 (H+) and separation on Dowex-1 ion-exchange resin and by paper chromatography.

Computation techniques in the conformational analysis of carbohydrates

Russian Journal of Bioorganic Chemistry, 2007
A growing number of modern studies of carbohydrates is devoted to spatial mechanisms of their participation in the cell recognition processes and directed design of inhibitors of these processes. Any progress in this field is impossible without the development of theoretical conformational analysis of carbohydrates.

The Conformational Free Energy of Carbohydrates

Mini-Reviews in Organic Chemistry, 2011
1. Abstract Although free energy calculations have been extensively employed to explore the conformational space of proteins, to date carbohydrates have received considerably less attention. This review provides a survey of recent computational free energy studies of the preferred conformations and characteristic dynamics of carbohydrate molecules in ...
