Abstract:	The chemical structure of lipid A, from the marine -proteobacterium Pseudoalteromonashaloplanktis 14393, a main product of lipopolysaccharide hydrolysis (1% AcOH), was determined using chemical methods and NMR spectroscopy. The lipid A was shown to be -1,6-glucosaminobiose 1,4-diphosphate acylated with two (R)-3-hydroxyalkanoic acid residues at C3 and C3 and amidated with one (R)-3-hydroxydodecanoyl and one (R)-3-dodecanoyloxydodecanoyl residue at N2 and N2, respectively.

Keywords:	¹H ³¹P ¹³C NMR spectroscopy lipid A lipopolysaccharide marine Gram-negative bacterium Pseudoalteromonas haloplanktis
