I have been criticised for the way I have written this structure. It
may be more clearly represented by:
This shows that the fucose is alpha1-3 linked to the GlcNac
residue as a branch, and not as part of the chain.
I have also been critisised for my representation of N-acetyl-neuraminic
acid as NeuAc and not NeuNAc. It is possible that a reader may not clearly
derive information regarding the fact that the acetyl group is N-linked
and not O-linked.
Therefore the structure for sialyl Lewis ^x may be represented by:
