The 5-aminopentyl group at the reducing end is a spacer to enable further conjugation to a carrier protein for immunological studies. It is an alpha-D-glucoside and a tetrasaccharide derivative. It is functionally related to a beta-D-Glcp-(1->4)-[alpha-D-GlcpA-(1->3)]-beta-D-Manp-(1->4)-alpha-D-Glcp."}]
