A 3DSS biomimetic peptide is designed based on the highly acidic, bioactive bone and dentin extracellular matrix protein, phosphophoryn.
Activity tests indicated the superior selectivity of the V2O5 systems based on the more acidic supports (Al2O3 and TiO2).
The cleavage of the amide to form the primary amine was achieved in the same step, based on the strong acidic condition after hydrolysis of phosphorus trichloride.
Most acidic PNGases were described to have a pH optimum between 4.0 and 5.0 [ 15, 16, 26, 27], which is probably based on the slightly acidic environment in vacuoles or their extracellular environment after secretion [ 15, 28].
For extraction of targets in chocolate samples a new, fast and simple procedure based on the use of acidic extraction medium and sonication was developed.
The results are well explained based on the structural and acidic properties of the MCM-22 derived zeolites together with the reduction behaviors of the catalysts.
The AE adhesive resin involves a separate etch and rinse process, whereas the SE approach is based on the use of acidic monomer that eliminates the etching process.
The catalytic activities, calculated based on the amount of acidic protons (measured by pyridine adsorption), were similar (102 and 95 mmol mol−1 mol−1).
Based on the amino acid sequence, TRP47 contains a typical percentage (15%) of acidic residues, but a much lower (3%) percentage of basic residues (Table 4).
The concentration of ions Zn2+ and Ag+ was determined by extraction-photometric method based on the dithizone reaction in acidic medium [18, 19].
