H. Parolis et Las. Parolis, THE STRUCTURE OF THE O-SPECIFIC POLYSACCHARIDE FROM ESCHERICHIA-COLI O113 LIPOPOLYSACCHARIDE, Carbohydrate research, 267(2), 1995, pp. 263-269
The O-specific polysaccharide from Escherichia coli O113 lipopolysacch
aride was separated from the core and lipid A by mild acid hydrolysis
and purified by GPC. Methylation analysis and H-1 and C-13 NMR spectro
scopic studies of the O-deacetylated polysaccharide allowed the determ
ination of the structure of the pentasaccharide repeating unit of the
polysaccharide which can be written as [GRAPHICS] The position of the
O-acetyl groups was not determined.
