Abstract/OtherAbstract:
Monosaccharide analysis is a critical way to profile the composition of complex carbohydrates. Methods to analyze neutral and amino sugars have been established for a long time, but methods for acidic sugars are rare. The acidic sugars, including uronic acids and sialic acids, are also important components in some complex carbohydrates. In this report, a high performance anion-exchange chromatography method with pulsed amperometric detection (HPAEC-PAD) was initially developed to analyze acidic sugars including different uronic acids and sialic acids. Subsequently, a method to profile complete monosaccharides, including most neutral, amino, and acidic sugars, was developed. This method is to profile a complete set of monosaccharides, and has a limit of quantitation of ~12.5 pmol for each sugar as well as good linearity over a wide range. This is a convenient procedure because it avoids additional derivatization of monosaccharides and has a broad application to a wide range of complex carbohydrates. The monosaccharide compositions of a variety complex carbohydrates such as different glycosaminoglycans, alginate, fucoidan, and N-glycans were profiled by this comprehensive method. In addition, the hydrolysis patterns of these complex carbohydrates are discussed.
