This study was aimed to investigate the AAs levels and the underlying metabolic relationship in hyperlipidemic subjects. METHODS An ultra-high performance liquid chromatography-tandem mass spectrometric (UPLC-MS/MS) method was developed for the determination of phenylalanine (Phe), valine (Val), histidine (His), tryptophan (Trp), and meth
