Structure of the molecular ions associated with the initially intact C22G1 molecule (a) and with the final ester hydrolysis products (b) identified in the amphiphilic dendron degradation pathway along the time course of the electrospray mass spectrometry (ESMS)-based assay using a solution of G22G1 originally dissolved into ammonium bicarbonate at pH = 7.4.
