    Understanding 1H NMR Spectra for Ethyl Acrylate: Hot aq. HCl Treatment Effects

    I've got the spectra for C5H8O2 (the spectral database confirms that it's ethyl acrylate) and treatment with hot aq. HCL causes the signals in the 1N NMR spectrum at d 1.3 and 4.2 to disappear. Does anyone know why this happens? Thanks!

    What Does Edman Degradation Reveal About Peptide Sequence?

    I'm looking at a (uni) past paper and it has one of those typical Qs - a molecular weight determination has shown that an unknown peptide E is a pentapeptide and that it contains the amino acids glycine, tryptophan, proline, valine and alanine. Treatment of pentapeptide E with carboxypeptidase...
