FIGURE 25.6 Molecular models of the disaccharides maltose and cellobiose. Two D-glucopyranose units are connected by a glycoside linkage between C-1 and C-4. The glycosidic bond has the a orientation in maltose and is p in cellobiose. Maltose and cellobiose are diastereomers.

The hydration of a-maltose has been investigated using molecular modelling and thermodynmnic methods. Due to crystallinity, the observed non-freezing water content was lower than that calculated. ... 

Maltose consists of two molecules of glucose that are linked by an 0C-(1,4 ) glycosidic bond. Maltose results from the enzymatic hydrolysis of amylose, a homopolysaccharide (Section 26.9), by the enzyme amylase. Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond. Commercial maltose is produced from starch that has been treated with barley malt. Figure 26.8 shows both a bond-line structure and a molecular model of maltose. 

Meiler et al applied the model-free approach to the dynamic interpretation of residual dipolar couplings in globular proteins. Ishima et aO compared the methyl rotation axis order parameters derived from the model-free analyses of the and longitudinal and transverse relaxation rates measured in the same protein sample. Best et al reported the results of molecular dynamics simulations compared with NMR relaxation experiments for maltose and isomaltose. Using the model-free formalism they could estimate reliable order parameters. Baber et used an extended model-... 

Thus, the structure shown in Fig. 12a was proposed by Whelan and coworkers to represent diagrammatically the structures of glycogen and amylopectin. It may be seen that this model, which has been drawn in the most symmetrical way possible and in which all B-chains carry, on average, 2 other chains (either 2 A-chains or 2 B-chains), accounts for the liberation of maltose after feefa-amylase treatment of isoamylase-debranched Meyer model, wherein chains do not terminate within the molecule, this feature is characteristic of the new structure. The result is that the molecular size should not be... 

Modifications have been made to the AMBER force field to improve the correlations between calculated and observed molecular properties of a-linked saccharides these led to refinements in solvation studies on maltose, a-, p- and Y-cyclodextrin and two larger cyclodextrins (DP 10 and 21). A molecular dynamics simulation investigation of the solvation patterns of the model disaccharide 4 in aqueous DMSO defined regions in which competition exists...
