RCSB PDB has integrated 3D structural information with glycosylation resources to promote interactions between the glycoscience and PDB communities.
Relevant PDB structures are now linked to individual data in
- GlyTouCan: the international glycan structure repository
- GlyCosmos: portal aiming to integrate the glycosciences with the life sciences, consisting of Standards, Repositories and Data Resources, providing information about genes, proteins, lipids, pathways and diseases.
- GlyGen: data integration and dissemination project for carbohydrate and glycoconjugate related data integrated from multiple international data sources
Data are accessible from individual Structure Summary pages.

This work builds upon other new improved features for exploring carbohydrate data in the PDB
