Structure of 3,6-dideoxy-3-[(R)-2-hydroxypropanoylamino]-D-galactose-containing O-polysaccharide from marine bacterium Simiduia litorea KMM 9504 T .

The O-polysaccharide was isolated from the lipopolysaccharide of a marine bacterium Simiduia litorea KMM 9504 ^T and studied by chemical methods along with 1D and 2D ¹ H and ¹³ C NMR spectroscopy including ¹ H, ¹ H-TOCSY, ¹ H, ¹ H-COSY, ¹ H, ¹ H-ROESY, ¹ H, ¹³ C-HSQC and ¹ H, ¹³ C-HMBC experiments. The following new structure of the O-polysaccharide of S. litorea KMM 9504 ^T containing D-galacturonamide, 2-acetamido-2,6-dideoxy-D-glucose and 3,6-dideoxy-3-[(R)-2-hydroxypropanoylamino]-D-galactose was established.
