Extracted ion chromatograms of selected metabolites obtained from
microsomal incubates: ketamine (m/z 238), norketamine
(m/z 224), hydroxynorketamine (m/z 240),
tetradeuterated hydroxynorketamine (m/z 244), trideuterated
hydroxynorketamine (m/z 243), hydroxyketamine
(m/z 254), tetradeuterated hydroxyketamine
(m/z 258), trideuterated hydroxyketamine
(m/z 257), and dehydronorketamine (m/z
222). Dotted lines are drawn through the peaks discussed in the main text.
