Amino acid analysis with high performance liquid chromatography with electrospray ionization mass spectrometry (LC-ESI-MS) is an emerging method. For more sensitive analysis, derivatization is used and next to commercially available derivatization reagents such as dansyl chloride (DNS), 9-fluorenylmethyl chloroformate (FMOC-Cl)

Enterococcus faecalis is a commensal bacterium of the human gut that requires the ability to pass through the stomach and therefore cope with low pH. E. faecalis has also been identified as one of the major tyramine producers in fermented
A method for determination of the non-protein amino acid l-α-amino-γ-(guanidinooxy)-n-butyric acid (L-canavanine) and other free amino acids in Vicia disperma is presented. Seed extracts were derivatized by reaction with diethyl ethoxymethylenemalonate and analyzed by reverse-phase high-performance liquid chromatography. Calibration curves

For liquid chromatographic analysis of amino acids involving derivatization and mass-spectrometric detection, it becomes more important to evaluate the presence of matrix effects in complex samples. This is somewhat complicated for amino acid analysis where analyte free sample matrix is
For patients with celiac disease, gliadin detoxification via the use of gliadinases may provide an alternative to a gluten-free diet. A culture medium, in which gliadins were the sole source of nitrogen, was developed for screening for microorganisms with gliadinase
