Polysaccharide side-chains

Fig. 6 Quantitative NMR spectra of pectic fractions obtained from olive pulp at three ripening stages for two harvest years, showing the disappearance of terminally-P-linked L-Ara/from olive pectic polysaccharide side chains [38]...

The repeating unit of the O-specific polysaccharide side-chains of the Salmonella typhimurium antigenic outer bacterial cell wall is as follows ... 

Purified endotoxin consists only of lipopolysaccharide. This itself has three distinct chemical regions an inner core called lipid A. an intermediate polysaccharide layer, and an outer polysaccharide side chain. Lipid A, a highly substituted disaccharide of gluct amiiie, is responsible for pyrogenicity and other immunological and biological properties associated with endotoxin. 

Polysaccharide moiety. The polysaccharide portion of lipopolysaccharide is known to be important in the virulence of many bacteria. Strains lacking polysaccharide side chains (rough strains) are invariably less virulent than those containing such structures.
