?-L-Fucp-(1->?)-?-D-Galp-(1->?)-D-GlcNAc
?-l-fucp-(1->?)-?-d-galp-(1->?)-d-glcnac
An amino trisaccharide consisting of <small>L</small>-fucopyranosyl, <small>D</small>-galactopyranosyl and 2-acetamido-2-deoxy-<small>D</small>-glucopyranosyl residues joined in sequence by glycosidic bonds. The positions of attachement and the alpha/beta configuration of the linkages are unknown. In the structure shown, one of the <i>R</i> groups is an <small>L</small>-fucopyransyl-<small>D</small>-galactopyranosyl group; the remaining two <i>R</i> groups are hydrogens.
