Enzymatic synthesis and characterization of oligosaccharides structurally related to the repeating unit of Pullulan

Capillary Electrophoresis of Mono- and Oligosaccharides

This chapter reports an overview of the recent advances in the analysis of mono- and oligosaccharides by capillary electrophoresis (CE); furthermore, relevant reviews and research articles recently published in the field are tabulated. Additionally, pretreatments and procedures applied to uncharged and acidic carbohydrates (i.e., monosaccharides and lower oligosaccharides carrying carboxylate, sulfate, or phosphate groups) are described.Representative examples of such procedures are reported in detail, upon describing robust methodologies for the study of (1) neutral oligosaccharides derivatized by reductive amination and by formation of glycosylamines; (2) sialic acid derivatized with 2-aminoacridone, released from human serum immunoglobulin G; (3) anomeric couples of neutral glycosides separated using borate-based buffers; (4) unsaturated, underivatized oligosaccharides from lyase-treated alginate.

Capillary electrophoresis of neutral carbohydrates: mono-, oligosaccharides, glycosides

This chapter reports an overview of the recent advances in the analysis of neutral sugars by capillary electrophoresis (CE); furthermore, some relevant reviews and research articles in the field are tabulated. Comparison of CE with chromatography is also presented, with special attention to separation efficiency and sensitivity. The main routes aimed at pretreatment and CE analysis of uncharged mono-, oligosaccharides, and glycosides are described. Representative examples of such procedures are reported in detail, upon describing robust methodologies for the study of (1) neutral mono- and oligosaccharides derivatized by reductive amination and by formation of glycosylamines; (2) underivatized mono- and di-saccharides analyzed using highly alkaline buffers; and (3) anomeric couples of glycosides separated using borate-based buffers.
