Nomenclature for Xyloglucan Oligosaccharides

This data base uses the nomenclature (S. C. Fry, W. S. York, et al., 1993, Physiol. Plant. 89: 1-3) in which each of the differently substituted β-D-glucosyl residues is indicated by a single letter. These code letters are illustrated below. Reducing glucose residues that have been converted to alditol moieties are indicated by the code "Gol". Xyloglucan oligosaccharides are unambiguously named by listing the code letters for each glucosyl residue, starting with the non-reducing end.


One Letter Codes for Xyloglucan Substructures

Thus, the trisaccharide:

α-D-xylopyranosyl-(1,6)-β-D-glucopyranosyl-(1,4)-D-glucitol

is completely defined by the code "XGol".

To see how this works, enter a xyloglucan sequence (capital letters only) to be displayed. (The default sequence is 'XLFGol'.)
