Percentage of structures of different origin in the CCSD that contain these glycosyl residues.
Although the numbers are highly dependent on the selection of structures in the data base they
do give a general idea of what to expect when analysing glucans of different origin.
E.g. compounds of mammalian origin often contain L-Fucp but no L-Rhap and rarely
pentoses or uronic acids. Even among bacterial polysaccharides there is a marked difference, e.g. in the
frequency of D-GlcAp residues in LPS and CPS.
