Web1 Introduction. Protein sequence analysis employing Edman degradation chemistry commonly uses high-performance liquid chromatography (HPLC) separation as the means for identification of the PTH-amino acid (phenylthiohydantoin amino acid) produced at each cycle. In fact, all modern automated protein sequencing instruments come with “;on-line ... WebAspartame (Nutrasweet®) is a remarkably sweet-tasting dipeptide ester. Complete hydrolysis of aspartame gives phenylalanine, aspartic acid, and methanol. Mild incubation with carboxypeptidase has no effect on aspartame. Treatment of aspartame with phenyl isothiocyanate, followed by mild hydrolysis, gives the phenylthiohydantoin of aspartic acid. i shall forget you presently my dear meaning
