Figure 3.
Mass spectrum obtained from the total lipid extract of pork chop sections using LC-MS/MS. Precursor ion scanning at m/z 184.1 in positive ion mode was performed. Peaks with black m/z values indicate diacyl-phosphatidylcholine (PC) species, while those with blue m/z values indicate alkylacyl- and/or alkenylacyl-PC species. All species were detected as [M + H]+ ions.
