  1. Linkage types and relative abundances are shown as percentages (rounded to two decimals) of the total disaccharide fragment count for mammals (values in parentheses) or bacteria [values in brackets]. Linkages are listed only for disaccharide fragments present at > 0.1% in either taxonomy group. Values of 0.00 indicate the presence of a linkage at < 0.005%; missing values indicate the absence of that linkage type in the corresponding taxonomy group. An entry (*) denotes that the linkage was reported for mammals in [2] but was not found in the databases. The percentages are cumulative for all ring types (including alditols), all absolute configurations and for all anomeric configurations of the acceptor. For linkages that occur only in mammals or only in bacteria, those with abundences of 0.40% or more are underlined.
