Mass scan obtained by LC-MS/MS analysis in which two glycated peptides (E↓K(glucose)TKIPAVF↓K and E↓RGFFYTPK(glucose)A↓C-terminal site for horse myoglobin and bovine insulin, respectively) are co-eluted. Doublet signals are enlarged to show the glycation efficiency of [12C6]glucose and [13C6]glucose.
