We used a liquid chromatography with a triple quadrupole tandem mass spectrometry ( LC - MS / MS ) for the detection of metabolites and glutathione conjugates of BPA and its analogs ( BPF , BPAF , BPZ and DMBPA ) in human liver microsomes ( HLM ) or with recombinant CYP isozymes in the presence of NADPH and GSH as a trapping agent .
 glutathione, BPA, BPF, BPAF, BPZ, DMBPA, NADPH, GSH
