This is a metabolomics study for monitoring altered amino acid (AA) and organic acid (OA) metabolism of in eyes from aging an mouse model at 8 and 18 weeks and 18 months. Simultaneous metabolic profiling analysis of OAs and AAs was performed as ethoxycarbonyl/methoxime/tert‐butyldimethylsilyl derivatives by gas chromatography–tandem mass spectrometry. A total of 42 metabolites—24 AAs and 18 OAs—were...
An efficient method for the simultaneous analysis of seven 2‐hydroxy fatty acids (2‐HFAs) as tert‐butyldimethylsilyl (TBDMS) derivative was developed by gas chromatography–mass spectrometry in selected ion monitoring mode. New mass spectral data on 2‐hydroxycapric, 2‐hydroxypalmitic, 2‐hydroxystearic and 2‐hydroxybehenic acids as di‐TBDMS derivatives for hydroxyl and carboxyl groups were built. Under...
