From: Machine Learning Classifies Core and Outer Fucosylation of N-Glycoproteins Using Mass Spectrometry
Representative CID MS/MS spectra of N-glycopeptides classified as (A) core fucosylation with bi-antennary type (VCQDCPLLAPLNDTR_5_4_1_2) and (B) outer fucosylation with tri-antennary type (VCQDCPLLAPLNDTR_6_5_1_3) of alpha-2-HS glycoprotein in human plasma (green circle, mannose; yellow circle, galactose; blue square, N-acetylglucosamine; red triangle, fucose; pink diamond, N-acetylneuraminic acid; red arrow, fucosylation diagnostic ions; and red box, pair of fragmented ions with or without fucose).
