Figure 3

(A) Mass spectrum of the CID of 10-HDoHE-AMPP exhibiting a diagnostic fragment ion at m/z 349 which was selected for the SRM transition based identification and quantitation of 10-HDoHE. (B) Mass spectrum of the CID of 11-HDoHE-AMPP displaying an informative fragment ion at m/z 361 which was selected for SRM transition based identification and quantitation of 11-HDoHE.
