Chimeric structural isomer fragments as cost-efficient internal standards for amino acid quantification by mass spectrometry
Luis Alberto De León-Jiménez, Robert WinklerAmino acid (AA) profiles from body fluids are clinical indicators of metabolic and hepatic diseases. This study proposes structural isomers as internal standards in tandem mass spectrometry (MS/MS) for quantification of AAs in preventive medicine.
