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) ...
In proteins, hydrogen bonds form between the backbone oxygens and amide hydrogens. When the spacing of the amino acid residues participating in a hydrogen bond occurs regularly between positionsiandi+4, an alpha helix is formed. When the spacing is less, between positionsiandi+3, then a 310 ...
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 o...
it is an electrostatic attraction. The hydrogen bond has only5% or so of the strength of a covalent bond. However, when many hydrogen bonds can form between two molecules (or parts of the same molecule), the resulting union can be sufficiently strong as to be quite stable. The length of...
(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 ...
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...
Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces. Hydrogen bonds can exist
What atoms does actinium bond with? How do hydrogen bonds between water molecules occur? How many hydrogen bonds can methanol form? Does CH3CH2NH2 have hydrogen bonding? What type of bond, ionic or covalent, forms between nitrogen and oxygen?
However, X-ray analysis of crystalline diketo-piperazine, a substance related to the proteins, shows that the molecules are linked together by hydrogen bonds between their respective oxygen atoms and =NH groups, to form flat continuous chains throughout the structure. ···0 CH"2 - . /H·...
