The molecule is a glycolipid with an unusual non-glycerol aglycone, 10-hydroxynonadecan-2-one that is glycosylated at the C10 hydroxy group by a branched tetrasaccharide residue. It is isolated from the marine sponge Caminus sphaeroconia and exhibits potent activity as an inhibitor of a type III bacterial secretory system. It has a role as a metabolite and an antibacterial agent. It is a glycolipid, a butyrate ester, an acetate ester, a beta-D-glucoside, a tetrasaccharide derivative and a methyl ketone.
