Explain whether acid can catalyze each of the following reactions; i.e., whether the reaction is faster at (pH lower than 7) than at pH 7:
1. Conversion of asparagine to aspartic and isoaspartic acid in peptides.
2. Conversion of aspartic acid to isoaspartic acid in peptides.
3. Cleavage of the peptide backbone at the aspartic acid residue.
