Sugars saccharide abbreviations

Scheme 4.1 (a) Structure of the lipopoly saccharides of Gram-negative bacteria, (b) The structure of the lipid A from E. coli. (c) The structure of Kdo residue (a-3-deoxy-D-manno-oct-2-ulopyranosonic acid). For all structures, where not stated otherwise, sugars are a-D-pyranosides. Residues in bold are present as non-stoichiometric substitutions. Common abbreviations P, Phosphate, PPEtn, 2-aminoethanol diphosphate, PEtN, 2-aminoethanol phosphate, PCho, 2-trimethylaminoethanol phosphate Gly, glycine, Ac, Acetyl, Cm, Carbamoyl, Pyr, Pyruvic Acid... 

As has become customary in these volumes, an abbreviated method is now used for representing higher saccharides. Sugars will be numbered as follows, and linkages will be indicated in the usual way ...
