Aggregations of the compounds having two functional groups such as carboxyl group, hydroxyl group, and/or amino group on the surface of alumina and silica gel, and their influence for selective reactionsThe adsorption states and selective reactions of compounds such as terephthalic acid (TPA), ...
Compared to their respective standards, the carboxyl peak for all the coprecipitates is reduced in amplitude and broadened indicating that the acids are adsorbed to ferrihydrite via carboxyl ligand exchange between the OH of the carboxyl group and the OH of an adsorption site14. It is also ...
These constants, however, should be considered with care. First, they were obtained by assuming that either the α- or the β-anomer is solely present, therefore they are upper estimates and refer to an average effect of the Ca(II) complexation on the 13C chemical shifts. Second, although...
When precursors bear the same highest-priority functional groups, the precursors with a greater number of highest-priority groups should be listed first. For example, CPDs prepared from ethylenediaminetetraacetic acid (EDTA; 4 carboxyl groups) and ammonium citrate (AC; 3 carboxyl groups) should be ...
In contrast to accB and accC, the genes coding for the carboxyl transferase are not part of an operon, and no transcriptional regulation has been found by sequence analysis [49]. Instead, the translation of the respective mRNAs is controlled by the β-subunit (AccD) of the mature carboxyl ...
5c). The activation energy barrier for deprotonation of the Wheland intermediate by the oxygen atom from the carboxyl group of E346 is 9.4 kcal/mol and the reaction energy is −24.3 kcal/mol. In the transition state structure (TS2), the bond between the tryptophan hydrogen atom ...
Biochar is enriched with organic carbon, contains nitrogen, phosphorus, and potassium as nutrients, and has a high porosity and moisture-holding capacity. The large number of active hydroxyl, carboxyl, sulfonic acid group, amino, imino, and acylamino hydroxyl and carboxyl functional groups are ...
Interestingly, such STX recognition pattern is similar to that found in voltage-gated sodium (NaV) channels [2], [43], where the binding mechanism is mediated by electrostatic interactions between the five- and six-membered guanidinium rings of STX and carboxyl groups on the NaV channels [44]...
