When good coordination is achieved between the donor and acceptor, hydrogen bonds are formed between the two atoms, between the atom and the group, or between the two groups. Moreover, the strength provided by hydrogen bonds is low compared to that of most covalent bonds, providing the basis...
At room temperature, however, only two hydrogen bonds were formed, compared to 19 bonds when the reaction occurred at body temperature. More bonds equal higher specificity. Hen Egg-white Lysozyme Strong hydrogen bonds are formed between a particular glutamine in the hen egg-white lysozyme (HEWL) ...
aDue to the fewer hydroxy groups existing in the system, there were fewer hydrogen bonds formed between PEG and HTCC, so a looser hydrogel structure was formed. 由于存在于系统的少数羟小组,有少量氢键被形成在钉和HTCC之间,因此一个更加宽松的水凝胶结构被形成了。[translate]...
The meaning of HYDROGEN BOND is an electrostatic attraction between a hydrogen atom in one polar molecule (as of water) and a small electronegative atom (as of oxygen, nitrogen, or fluorine) in usually another molecule of the same or a different polar su
are thus employed, on which the occurrence of the surface carboxyl groups (-COOH) functions to realize the stable distribution of particles inside the polymer skeleton even for the directly cured structure (Supplementary Figure2). This can be ascribed to the formation of hydrogen bonds between the...
In our model, the H-bonds are formed between the O(2)-atoms on different x-y planes along the curdlan helix, hence the H-bonds are not perpendicular to the helix axis. The new H-bonds are connected along the helix, traversing three curdlan chains to make a left-handed helix. ...
Hydrogen bonds: Hydrogen bonds are formed as a result of the attractive force occurring between a hydrogen atom which is already covalently bonded to a very electronegative atom like oxygen, fluorine, or nitrogen and another very electronegative atom like those. This other atom can be oxyge...
Although hydrogen bonds form between hydrogen and any other electronegative atom, the bonds within water are the most ubiquitous (and some would argue, the most important). Hydrogen bonds form between neighboring water molecules when the hydrogen of one atom comes between the oxygen atoms of its ...
regularly between positionsiandi+4, an alpha helix is formed. When the spacing is less, between positionsiandi+3, then a 310 helix is formed. When two strands are joined by hydrogen bonds involving alternating residues on each participating strand, a beta sheet is formed.(See also protein ...
(Chemistry) a weak chemical bond between an electronegative atom, such as fluorine, oxygen, or nitrogen, and a hydrogen atom bound to another electronegative atom. Hydrogen bonds are responsible for the properties of water and many biological molecules ...
