✦ Synopsis

The structural characterization of large synthetic oligosaccharides and related glycoconjugates performed by the use of electrospray ionization mass spectrometry (ESIMS) is described. The largest molecules described here are unprotected and protected pentaantennary pentacosasaccharides 2 and 5 with average molecular masses of 4441 and 9416, respectively. The straight-chain neutral ceramide decasaccharide (d18: l/c24: 0) 6 and the disialoganglioside GD2 (d18: l/c24: 0) 7 were also successfully analyzed by ESIMS. In addition to exact imass determination, collision-induced dissociation (CID) spectrometry of these compounds provided saccharide chain sequence information.
