The molecule is a glycoside that consists of an alpha-D-mannose residue and five N-formyl-alpha-D-perosamine residues all linked sequentially (1->2) and linked at the reducing end glycosidically to a 5-(methoxycarbonyl)pentyl group. It is a glycoside, a methyl ester and a hexasaccharide derivative.
