Region-specific glycan maps were obtained with ∼120 N-glycan compositions in each region, revealing significant differences in “brain-type” glycans involving high mannose, bisecting, and core and antenna fucosylated species. Additionally, the cell membrane N-glycome of three functional regions of...

(MM7) is C10H9N2O2. In the MS2 spectra of MM6, the neutral losses of 18 Da and 46 Da in MM6 are detected by loss of the H2O and C2H6O side chain. In the MS2 spectra of MM7, the neutral loss of 44 Da is recommended as the loss of the COO group, indicating a carboxyl group...
