| Entry | The KEGG GLYCAN database is a collection of glycan structures. Each entry is identified by the unique identifier called the G number ('G' followed by five-digit number). The database started by taking all unique structures in CarbBank, and has been expanded for representation of glycan structures in KEGG pathways and Brite hierarchies. |
|---|---|
| Name | The recommended name and alternative names of the glycan. |
| Composition | The composition of monosaccharides. |
| Mass | The mass computed from the composition, excluding those in parentheses. |
| Structure | The molecular structure (carbohydrate sequence) of the glycan is manually drawn and stored in the KCF format (KCF file button). A GIF image of the structure is shown, together with KCaM button for searching similar structures and SNFG button to display in Symbol Nomenclature. |
| Remark | The same glycan in the COMPOUND database, if any, is shown. Monosaccharides and small oligosaccharides are registered in both the COMPOUND and GLYCAN databases. |
| Comment | Text information commenting on the glycan. |
| Reaction | Links to the REACTION database entries, where the glycan appears as a substrate or a product. |
| Pathway | Links to the KEGG pathway maps, where the corresponding glycan is marked in red. |
| Module | KEGG modules that contain this glycan entry. By clicking on the link, the corresponding circular object is marked red in the module diagram. |
| Network | KEGG network variation maps that contain this glycan entry. By clicking on the link, the corresponding glycan name is frmaed red in the map. |
| Enzyme | Links to the ENZYME database entries, where the glycan appears as a substrate or a product. |
| Brite | This field contains compound classifications in the BRITE database. |
| Reference | Refereces about this glycan. |
| Other DBs | Links to outside databases, especially CarBank which is also known as CCSD (Complex Carbohydrate Structure Database). When the CCSD link is clicked all CarbBank entries with the same glycan structure will be displayed. |
| LinkDB | 'All DBs' button in this field retrieves all available links to related database entries in the LinkDB system. At GenomeNet this field does not appear; instead a list of actual links is displayed on the right. |
| KCF data | The KCF (KEGG Chemical Function) representation of the glycan structure can be displayed here. |
