The structure of sialyl Lewis x is:
This is for the simplest glycosphingolipid carrying the antigen. The
outermost galactose and the fucose are both attached to the GlcNAc
residue, at the 4 and 3 positions respectively. Nomenclature is based on
the IUPAC-IUB commision (published in JBC vol. 262, pp. 13-18, 1987).
A good general reference for structures carried on glycosphingolipids is
"Glycosphingolipids: Structure, Biological Source, and Properties" by
Stults, et al. in Methods of Enzymology Vol. 179, pp.167-214. Under the
"comment" column of these extensive structural tables, trivial and blood
group antigen nomenclatures are listed.
