GlyTouCan provides stable accessions for glycans described at varyious degrees of characterization, including compositions (no linkage) and topologies (no carbon bond positions or anomeric configurations).
GNOme organizes these stable accessions
- for interactive browsing,
- for text-based searching, and
- for automated reasoning
- with well-defined characterization levels.
GNOme is a subproject of and is supported by the GlyGen: Computational and Informatics Resources for Glycoscience project.
GNOme is an OBO Foundry ontology.
Interactive Tools
Use the GNOme Glycan Structure Browser to find glycan structures by composition, topology, and subsumption relationships.
Use the GNOme Glycan Composition Browser to find glycan compositions by composition and subsumption relationships.
Deep-linking is also supported, to jump to a specific GlyTouCan acccession: G62109NW or button state: HexNAc(5)Hex(6).
