    • Among the aldehydes attached to silica, only those exposed to attack by p-toluenesulfonylhydrazide would form the corresponding hydrazone. Nevertheless, the test provides information on the relative amounts of silica-based aldehydes readily reacting with the hydrazide.

    • Although a large amount of silica catalysts were used, only a small fraction (probably less than 1%) of aldehyde groups located on the silica would be accessible to protein substrates or peptide intermediates. Each protein molecule is cleaved into many fragments. Thus, it is not easy to compare the amounts of catalytic sites and substrates available under the experimental conditions.

    • 0illustrated in Figure 3 may be related to the participation of ionized and neutral forms of aldehyde hydrates. The pH profile, however, reflects ionization of functional groups of the protein substrate as well as the catalyst.
