As two complementary strands get longer, the additive nature of the H-bond
energies comes into play, and at some total number of potential H-bonds
between two single DNA strands, their energy surpasses the temperature dependent vibrational energies, and the two strands stick together.
Now, two equilibriums for the dissociation of the two kinds of H-bond
breaking occurred during the initial 900 ps of simulation.
The chemoselectivity of the esterification reaction was attributed to the H-bond
withdrawing electrons from the carbonyl, thereby promoting the nucleophilic attack by an OH group.
33 kcal/mol with respective to B and in this case two H-bond
were established, the first between O of CO[O.
Fenitrothion has apparent structural similarities with the pharmaceutical antiandrogen flutamide and the environmental antiandrogens vinclozolin and linuron (Figure 2) but differs most significantly in having a thiophosphonyl group as a proposed H-bond
acceptor in the D-ring region of the AR interaction site.
The O of the SO2 acted as a H-bond
receptor of hydrogen with the residues of the amino acid; Thr 56 in conjunction with Ser 59 (2.
effect on the dynamic mechanical properties and crystallization behavior of the nanocomposites were subsequently studied by dynamic mechanical analysis (DMA) and wide-angle X-ray diffraction (XRD), respectively.
On the other hand upon switching to the isomeric structures both the O/H distance and the Y-N1-H bond angle decrease while the N1-H bond length increases which indicates that the absence of the N2/H-N1 H-bond
in the isomeric structures causes strengthening of the O/H-N1 H-bond
Polyurethane-based azopolymers, containing no hydroxyl groups in the main chains and only less accessible NH groups as H-bond
donors, were anticipated to have more labile azo groups and hence to exhibit higher SRG efficiency than the epoxy- or aniline-based azopolymers.
is one of the essential concepts in science due to its valuable role in chemistry and biology, which makes it one of the enduring active research topics.
This may mean that all the N--H groups form the H-bond
with O, N, and Cl.
