The d-GlcNAc moiety in sialylLewisx (sLex, 1) acts predominantly as a linker to position the d-Gal and the l-Fuc moieties in the bioactive spatial orientation. The hypothesis has been made that the NHAc group of GlcNAc pushes the fucose underneath the galactose and, thus, contributes to the stabilization of the bioactive conformation of the core of sLex (1). To test this hypothesis, GlcNAc mimetics
