ABSTRACT
The lipid A component of Re-lipopolysaccharide from S.typhimurium SL 1102 was prepared by hydrolysis with a 0.1 mol/L acetate buffer.Chemical as well as advanced l3C-,and 31P-NMR investigations revealed a ?1' ,6-interlinked D-glucosamine diasaccharide, which is substituted by two phosphate(P)groups, one being esterlinked to the non-reducing residue,and another bound glycosidically to the C1 of the reducing residue, is as the central backbone.Its structure is shown as follows-P-GlcN(?1', 6)GlcN-P-The amino(2 and 2')and hydroxy(3 and 3')groups of the backone are substituted by 3-OH-14 0, and unhydroxy fatty acids appear to be the subtituents of the hydroxy group of 3-OH-140, in the means of formation of 3-acyloxyacyl ester and amides.
