The identity of an atom is determined only by the number of protons in its nucleus. 一个原子的特性仅由原子核中质子的数量来确定。 Hydrogen is hydrogen because it has just one proton, carbon is carbon because it has six, gold is gold because it has 79, and so on. 氢就是氢,因为它只有...
Such simplified spectra enable detection and unambiguous assignment of hydrogen atom binding site(s) using carbon-fluorine scalar couplings, and thereby provide a means of potentially assessing thermooxidative instability due to residual hydrogen. The relative concentration of carbon with attached hydrogen ...
Several possible influences relative to the catalyst structure are discussed in the literature, including property modification of Lewis acids15, interactions with Brønsted acid sites16, replacement of the proton of Brønsted acid sites and neu- tralization of the acid sites, and the formation of...
It is not easyto determine structures in solution and these have oftenbeen inferred from thermodynamic data.2*3 A correla-tion of the stability constants for corresponding copper-(11) and hydrogen-ion complexes of some aliphatic mono-carboxylates, determined potentiometrically in a 3M-sodium ...
The poor reactivity of Mb with H2O2 might be partly due to the malfunction of the distal histidine as a general acid-base catalyst and the absence of the distal arginine. Whereas the distal histidine in peroxidase is suggested to raise the basicity of imidazole by a hydrogen bond with the ...
