The molecule is a derivative of alpha,alpha-trehalose having an O-sulfo group at the 2 position and two long chain fatty acyl substituents at the 2'- and 3'-positions. It is a trehalose sulfate, an organosulfate oxoanion and a polyacyl alpha,alpha-trehalose derivative. It derives from an alpha,alpha-trehalose.
