The molecule is a tripartite compound comprising an alpha-D-Gal unit linked to beta-D-GlcNAc, which is in turn linked to a CETE (2-[(2-carbomethoxyethylthio)]ethyl; 2-{[2-(methoxycarbonyl)ethylsulfanyl]}ethyl) moiety. It is a glycoside, a disaccharide derivative, a methyl ester and an organic sulfide.
