Bacterial capsular polysaccharides (CP) are carbohydrate polymers comprised of repeating saccharide units. Several of these CP have side chains attached to their backbone structures. The side chains may include O-acetyl, phosphate, sialic acid, and other moieties. Those moieties represent the
Both hydroxymonocarboxylic acids and dicarboxylic acids in urine were converted into their 2-nitrophenylhydrazides without lengthy and cumbersome sample workup and were separated from each other by two-step extraction with diethyl ether at different pH values. HPLC analysis of each acid
Physical, chemical, antigenic, and immunologic characterization of polygalacturonan, its derivatives, and Vi antigen from Salmonella typhi.
Journal of chromatography. B, Biomedical applications, 679(1-2), 1-6 (1996-04-26)
Hydroxycarboxylic acids in urine of patients with non-insulin-dependent diabetes mellitus and of healthy subjects are analyzed as 2-nitrophenylhydrazides by an improved high-performance liquid chromatographic method which has advantages with respect to resolution and analysis time. Variations in levels of hydroxycarboxylic
