The structure of the carbohydrate backbone of the lipid A-core region of th
e lipopolysaccharide (LPS) from Proteus penneri strain 16 was determined us
ing NMR and chemical analysis of the core oligosaccharide, obtained by mild
acid hydrolysis of the LPS, and of the products of alkaline deacylation of
the LPS:
