The “glycam” oligosaccharide notation

Documentation in progress.  Please be patient.

The glycam oligosaccharide notation is recognized by GLYCAM-Web when building via URL.  It is based on common practice and should be familiar to most glycoscientists. It is based on the common abbreviations given in Table 1 at this location. Monosaccharides are named starting with anomeric configuration, then the chirality, the abbreviation and linkage information, etc.

The most important differences from common notation methods are:

  • There can be no spaces in the notation.
  • The identity of the moiety at the reducing end must be specified explicitly (e.g., -OH or -OME).

For example chitobiose would be,

The -OMe version would be:

Branches are handled with square brackets. To specify an alpha, L rhamnopyranoside with a-D-Manp-(1-3)-a-D-Manp- attached at the three position and b-D-Galp-(1-4)-b-D-Galp attached at position four, you would use:
