title: GLC-MS of reduced, acetylated, and methylated (2----4)- and (2----8)-linked disaccharides of 3-deoxy-D-manno-octulopyranosonic acid (Kdo).
abstract: Synthetic alpha- and beta-(2----4)- and alpha- and beta-(2----8)-linked disaccharides of 3-deoxy-D-manno-octulopyranosonic acid (Kdo), of which the synthesis of the beta-(2----4)-linked compound is described here, were used to develop a simple GLC-MS method for the determination of their anomeric configuration. The GLC and GLC-MS data for the reduced and acetylated or methylated derivatives of the above compounds indicate the alpha-linked synthetic disaccharides to be identical to those isolated from bacterial lipopolysaccharides.
