Proposed chemical formation scheme and HPLC-MS/MS analysis of DHA- and AA-derived dopamine adducts. A, proposed reaction scheme of DHA- and AA-derived dopamine adduct formation. B, the [MH]+ ion m/z 254, 210, 252, and 268 of SUD, PRD, HED, and GLD, respectively, were subjected to collision-induced dissociation, and the daughter ions were scanned (upper left panel). The proposed structures of individual ions are shown (upper right panel). The chemical structure composition of the dopamine adducts is proposed by fragmental analysis (lower panel).
