Chimeric structural isomer fragments as cost-efficient internal standards for amino acid quantification by mass spectrometry.

Amino acid (AA) profiles from body fluids such as blood and urine are clinical indicators for diagnosing metabolic and hepatic diseases. Current quantitative methods, such as liquid chromatography-mass spectrometry (LC-MS) with isotopically labelled internal standards (ISs), are costly and technically demanding. This study proposes a cost-efficient alternative using structural isomers as ISs in a direct liquid infusion (DLI) tandem mass spectrometry (MS/MS) approach. The method leverages chimeric spectra and fragment intensity ratios to quantify AAs, demonstrating high linearity and precision even with a 3D ion trap mass analyser. This approach offers a viable strategy for AA quantification in preventive medicine, particularly for screening metabolic diseases such as phenylketonuria, diabetes, and liver dysfunction.

Identification and quantitation of nucleosides, bases and other UV-absorbing compounds in serum, using reversed-phase high-performance liquid chromatography. I. Chromatographic methodology.

A comprehensive investigation of the high-performance liquid chromatographic separation of nucleosides, their bases and other low-molecular-weight UV-absorbing compounds that might be found in serum is reported. A buffer-methanol gradient was used in conjunction with chemically bonded, microparticulate columns to separate many of the biologically important compounds under study in minimal time with maximal resolution. Retention data, absorbance ratios (280/254 nm) and fluorescence responses are reported for 86 nucleosides, bases, nucleotides and other UV-absorbing compounds commonly encountered in biological studies.
