FIGURE 3. — AGE-modified tryptic peptides obtained from B. napus (A and B) and A. thaliana (C and D) soluble proteins distributed by classes of AGE modifications (A and C) and metabolic origin (B and D). The AGE patterns were identified by nanoscale UPLC-ESI-Orbitrap-LIT-MS operated in positive DDA mode. Glycation sites were identified by database search using the Sequest engine. ArgPyr, argpyrimidine; CMA, N^ϵ-carboxymethylarginine; GLAP, glyceraldehyde-derived pyridinium compound; Glarg, glyoxal-derived hydroimidazolone; Pyr, pyrraline.
