Chromatography is used to identify amino acid sequences in compounds.
1
The dipeptide cysteine-aspartic acid (cys-asp), J, and the dipeptide aspartic acid-cysteine (asp-cys), K, are shown.


(a) A mixture of the two dipeptides J and K is analysed by gas chromatography followed by mass spectrometry (GC-MS).
Explain why J and K can be separated by gas chromatography and why mass spectrometry using electrospray ionisation does not enable you to identify them.
