The structure of the O-specific side-chain of the lipopolysaccharide from Escherichia coli O:7 has been investigated, using n.m.r. spectroscopy, methylation analysis, partial hydrolysis, and Smith degradation as the principal methods. It is concluded that the polysaccharide is constructed of repeating pentasaccharide units having the structure (formula; see text) where D-QuipNAc stands for 4-acetamido-4,6-dideoxy-D-glucopyranose. The 13C-n.m.r. spectrum of the polysaccharide has been interpreted completely.
