Structure of the core-oligosaccharide with a characteristic D-glycero-alpha-D-talo-oct-2-ulosylonate-(2-->4)-3-deoxy-D-manno-oct-2-ulosonate [alpha-Ko-(2-->4)-Kdo] disaccharide in the lipopolysaccharide from Burkholderia cepacia.

The core oligosaccharide in the lipopolysaccharide (LPS) of Burkholderia cepacia GIFU 645(T) was investigated. After mild acid hydrolysis of the LPS, a heptasaccharide was isolated and identified by chemical analyses, GLC-MS, FABMS, and NMR spectroscopy as follows: [carbohydrate structure: see text] where L-alpha-D-Hep stands for L-glycero-alpha-D-manno-heptose, Ko for D-glycero-D-talo-oct-2-ulosonic acid, and Kdo for 3-deoxy-D-manno-oct-2-ulosonic acid.
