The hydrogen bond network is responsible for the exceptional physical and chemical properties of water, however, the description of hydrogen bond remains a challenge for the studies of condensed water. The investigation of structural and binding properties of water clusters provides a key for ...
The molecular configurations of water molecules in the disordered condensed state are investigated by neutron diffraction. The results provide evidence for the interplay of hydrogen-bond geometry with thermal disorder, leading to a sensitive response to external variables and local influences....
Microscopic characteristics of hydrogen bonds of hydrated borates A lot of confusion still exists in employing hydrogen bonds in chemical research, though hydrogen bond research has strongly expanded in depth as well as i... D Yu,D Xue,H Ratajczak - 《Physica B-condensed Matter》 被引量: 44...
A hydrogen bond is likely to be present between the side groups of these residues in the cold adapted enzyme. Here we report on the effect on kinetics and stability upon incorporation of a comparable ion pair into VPR by site directed mutagenesis. Three mutants were produced, containing a ...
In Section 4.1 “Covalent Bonds”, we stated that the covalent bond in the hydrogen molecule (H2) has a certain length (about 7.4 × 10−11 m). Other covalent bonds also have known bond lengths, which are dependent on both the identities of the atoms in the bond and whether the bond...

Negative enthalpy (Δ) and positive entropy (Δ) values indicated that both hydrogen bond and hydrophobic force played a major role in the binding process of CECT to HSA, which was consistent with the results of the molecular modeling study. In addition, the effect of other ions on the ...
Insect olfaction system plays a key role in the foraging food, pollination, mating, oviposition, reproduction and other insect physiological behavior. Odorant binding protein are widely found in the various olfactory sensilla of different insect antennae
H-bond characteristics36 low-energy isomers of (H2O) n (n=6–21) are optimized using ab initio methods. Their vibrational frequencies are calculated and the properties of hydrogen bond (H-bodoi:10.1007/s10876-016-0971-5Yang, Hui-hui
Fig. 1. Chromatography of monosaccharides. A: mixed standard; B: GLO. Structure of GLO Commonly, the anomeric hydrogen signals of sugar residues are usually located at 4.5–5.5 ppm in 1H NMR spectrum. Among them, chemical shift of the α-type signal is usually greater than 5.0 ppm, and ...
