GLYCAM-Web | Utilities for molecular modeling of carbohydrates

What are the shapes of my glycan?

Generate and display 3D structures of the expected shapes of a glycan and download files for viewing offline or for use in other modeling applications, such as for performing MD simulations with AMBER.


The tools below help you to assemble or select a glycan, which is then automatically energy minimized with the GLYCAM force field [1] to generate one or more 3D models. The file formats available for download include PDB (coordinates), as well as AMBER (topology and coordinates). The beta-test Carbohydrate Builder does not currently provide files for MD simulation.


  • A familiarity with carbohydrate nomenclature.


Carbohydrate Builder (Old School)
Assemble a glycan by connecting monosaccharides. This is the legacy tool.
Beta-test Carbohydrate Builder (New!)
Assemble a glycan by connecting monosaccharides. This new tool is still in development.
GAG Builder
Assemble a glycosaminoglycan by connecting monosaccharides.
Oligosaccharide Libraries
Select a glycan from libraries of common structures.
Build Via Text
Type-in or copy-paste a glycan sequence in GLYCAM text format.
