3D-SNFG: List of Residue Names

Description The following tables define the residue names that are recognized within the 3D-SNFG program, and are separated based on the source: PDB, GLYCAM, and CHARMM*. Some monosaccharide residues that are defined by the SNFG are uncommon, and not currently used by any of these sources. While the 3D-SNFG program is capable of drawing the […]

3D-Symbol Nomenclature For Glycans (3D-SNFG)

Description The Symbol Nomenclature For Glycans (SNFG) facilitates the efficient communication of carbohydrate structures, and has become widely accepted by the glycobiology community. The system is fully described in the NCBI text Essentials of Glycobiology. Carbohydrates currently lack a simplistic, standardized representation for 3D structure, and are thus predominantly visualized with atoms displayed. Discerning the […]
