Disac3DB is an annotated data base that contains the 3D structural information of disaccharides. These disaccharides constitute molecules in their own rights and they constitute the building blocks of the vast majority of oligosaccharides, complex carbohydrates such as 'glycan determinants' (blood group antigens, core structures, fucosylated oligosaccharides, sialylated oligosaccharides, Lewis antigens, GPI-anchors, N-linked oligosaccharides, globosides,...), glycosaminoglycans, plants and algal polysaccharides and some bacterial polysaccharides.
