alpha-d-rhap4r-(1->2)-alpha-d-rhap4nfo-(1->3)-alpha-d-rhap4nfo-(1->2)-alpha-d-rhap4nfoome
A carbohydrate derivative in which a tetrasaccharide derivative consisting of an α-<small>D</small>-rhamnose residue, two <em>N</em>-formyl-α-<small>D</small>-perosamine residues and a methyl <em>N</em>-formyl-α-<small>D</small>-perosaminide residue linked sequentially (1→2), (1→3) and (1→2) is linked to a protein, normally via a 3,4-diaminocyclobutane-1,2-dione-based linker attached to position 4 of the rhamnose residue at the non-reducing end.
