The molecule is a glycoside that consists of a beta-1,3-linked nonaglucan backbone with a beta-1,6-glucotetraose branch at the 6-O-position of the nonaglucan central sugar unit and with a 2-aminoethoxy moiety at the reducing-end anomeric centre. It is a glycoside and an oligosaccharide derivative. It derives from a beta-D-Glc-(1->3)-beta-D-Glc-(1->3)-beta-D-Glc-(1->3)-beta-D-Glc-(1->3)-[beta-D-Glc-(1->6)-beta-D-Glc-(1->6)-beta-D-Glc-(1->6)-beta-D-Glc-(1->6)-beta-D-Glc-(1->6)]-beta-D-Glc-(1->3)-beta-D-Glc-(1->3)-beta-D-Glc-(1->3)-beta-D-Glc-(1->3)-beta-D-Glc.
