Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

Molecular modelling using semiempirical methods AM1, PM3, PM5 and, MINDO as well as the Density Functional Theory method BLYP/DZVP respectively were used to calculate the structure and vibrational ...

Definition: Anomers are stereoisomers that occur due to differences in configuration at their anomeric carbon. Anomeric Carbon: Anomeric carbon is the carbon atom with an aldehyde or ketone group in ...

On-column mutarotation between the α- and β-anomers of the released side-chains’ reducing ends resulted in broad, tailing, split HPLC peaks and necessitated a reduction step to transform the ...

Using this unique approach in conjunction with oxygen-18 isotopic labeling, we show on a range of disaccharides how the two α and β anomers that every reducing glycan adopts in solution can be readily ...

Our method: (1) Chemically converts monosaccharides to sugar-1-phosphate anomers, bypassing chemical protection steps, the more substrate specific kinases, and advanced purification techniques; (2) ...

Lactose is a disaccharide that can exist in solid form as α-lactose and β-lactose anomers. The anomers result from a mechanism known as mutarotation, where the orientation of a hydrogen and a hydroxyl ...

Figure 1: Structural features of complex carbohydrates. Figure 2: Structure and IM–MS data of trisaccharides 1–6. The full benefit of this method will become apparent once CCS data for ...

Here we report this enzyme is not a β-1,3-N-acetylglucosaminyltransferase with catalytic activity towards β-galactose but rather a β-1,4-glucuronyltransferase, designated B4GAT1, towards both α- and β ...

HILIC columns with amino functional groups are often used to prevent the separation of anomers; however, one drawback of the amino functional group on the packing material is the low recovery rate of ...

ABSTRACT: The anomeric specificity of D-glucose metabolism in erythrocytes has been since 1985 the matter of extensive investigations reported in about ten publications. The present report aims at ...
