This software implements the Symbol Nomenclature For Glycans (SNFG), originally from the 3rd edition of the Essentials of Glycobiology. To use:
1.Type glycan or glycopeptide string in standard IUPAC-condensed nomenclature (Examples given below)
2.Change basic and advanced options, if necessary .
3.Press "Draw" to sketch.
4.Right click sketch to save figure.
Follow the link below to download the standalone version with a Graphical User Interface (GUI) version for version for PC, Mac and Linux operating systems. Instructional videos and program source code are also provided.
