Monoglucosides

Fig. 2.7.2. (—)-LC-ESI-MS chromatograms of a standard APG solution, (a) Total ion current trace fromm/2 200 to 600. (b)XIC of Cg-, C10-, and Ci2-monoglucoside, and (c) XIC of Cg-, C10-, and Ci2-diglucoside. Peak numbering as in Table 2.7.1 indices a and b denote different stereoisomeric forms.

In (+)-ionisation mode, a distinct selectivity of monoglucosides with respect to the formation of adduct ions was observed. Depending on the ring form (glucopyranoside or glucofuranoside) and the stereoisomerism (a- or (3-alkyl monoglucoside), a different affinity towards Na+ and... 

NH4 became apparent. The molecular structures of the four possible isomers of the alkyl monoglucosides are shown in Fig. 2.7.4.
