Methyl 7-O-(2-amino-2-deoxy-alpha-D-glucopyranosyl)-L-glycero-D-manno-hepto+ ++ pyranoside (1) was released from the lipopolysaccharide of the UDP-galactose epimerase-less mutant J-5 of Escherichia coli by methanolysis and isolated by high-voltage paper electrophoresis. Its chemical structure was de
