Naming scheme followed in EK3D to represent monosaccharides. (A) The four letter code encompasses the anomeric form of the sugar (α or β or 0) at the first position, followed by the name of the sugar at the second position. For instance, A at second position represents galactose. The third letter is assigned to chemical modifications such as phosphorylation and acetylation: A at the third position corresponds to O acetylation at the first carbon atom and J corresponds to N acetylation at the second carbon atom. The fourth letter indicates the furanose form of the sugar. (B) Examples for schematic and chemical representations of monosaccharides and the associated EK3D naming scheme.
