SMILES: C[C@@H]1[C@@H](C[C@H]([C@H](O1)O[C@H]2[C@@H]([C@H](O[C@@H]([C@H]2O[C@@H]3[C@@H]([C@H]([C@H]([C@H](O3)CO)O)O)O)O[C@H]4[C@@H](O[C@H]([C@@H]([C@@H]4O)O)O)C)CO)O)O)O
Description: The molecule is a branched tetrasaccharide consisting of alpha-D-galactose, alpha-D-mannose and alpha-L-rhamnose residues linked sequentially (1->2) and (1->4), to the mannose residue of which is also linked (1->3) an alpha-D-abequose residue. The structure constitutes a possible epitope of the O-antigen polysaccharide in Salmonella. It has a role as an epitope.
