The structure of the polysaccharide part of the LPS from Serratia marcescens serotype O19, including linkage region to the core and the residue at the non-reducing end Original Research Article

The structure of the LPS from Serratia marcescens serotype O19 was investigated. Deamination of the LPS released the O-chain polysaccharide together with a fragment of the core oligosaccharide. The following structure of the product was determined by NMR spectroscopy, mass spectrometry, and chemical methods:
