Accurate amino acid composition analysis for HPLC, UHPLC, and UPLCAccurately separating, identifying, and quantitating amino acids is challenging. The amino acid sequence is the primary structure of a protein and it is unique to a particular peptide or protein. Amino acids are also key ingred...
Capillary electrophoresis using indirect UV detection was applied for the analysis of 9 amino acids. This is a fast and convenient method for the analysis of amino acids, compared to HPLC. A reversed polarity mode was employed, with the sample being injected at the cathode and electrophoresed ...

L-L diastereomers and the non-formation of this hydrogen bond in the D-L diastereomer (the first letter refers to the configuration of the AA to be analysed, the second to that of the reagent AA amide) as well as by the low conformational freedom of amino acid residues in diastereomers....
Amino acid analysis is a powerful bioanalytical technique for many biomedical research endeavors, including cancer, emergency medicine, nutrition and neuroscience research. In the present study, we present a 3min analytical method for underivatized amino acid analysis that employs ultrahigh-performance liqui...
