a

The presence (+) or absence (−) of a particular sugar in a given organism is indicated in the “All” column for that organism; the “All” columns refer to whether or not that sugar appears in any or all of the following specific structural categories, as indicated: protein GPI anchors, free GIPLs, protein N-linked glycans, protein O-linked glycans, protein phosphodiester-linked glycans (P-glycan), and base J.
