Hydrogen bonding is that the interaction involving a atom placed between a combine of alternative atoms having a high affinity for electrons; such a bond is weaker than an bond or bond however stronger than van der Waals forces. element bonds will exist between atoms in numerous molecul...
The original examples of hydrogen bonding were found to involve the electronegative atoms F, O, or N. The current IUPAC definition given in the ‘Gold Book’ still specifically mentions these atoms, although it adds a caveat suggesting that the phenomenon is not limited to these atoms … Clearl...
An example is covalent bonding, where valence electrons are shared between two or more atoms. Electronegativity is the tendency of an atom in such a bond to attract the shared electrons preferentially to itself, such that partial charge separation occurs between the bonded atom...
Generally, various secondary structure types have different tendencies to engage in stable hydrogen bonding, with loops being less hydrogen bonded than helices and sheets which are, by definition, stabilized by amide hydrogen bonding. In the Pab1 structure, the hydrophobic sheets tend to be the most...
(Fig.5b), which reflects the plasticity of the hPXR LBD in molding to the shape of the ligand and may contribute to the favorable positioning of key protein–ligand interactions. Even though the residue H407 has been previously reported to participate in hydrogen bonding with several ligands, ...

The presence of the double bond in the sphingosine chain determines the tilt of ceramides in the membrane and enables the lipid to interact with enzymes such as hydrolases and phosphatases [7]. Moreover, unsaturation in the sphingoid backbone augments intramolecular hydration/hydrogen bonding in the...
Theoretical investigations typically concentrate on either a Flory– Huggins type analysis3,20 or cooperative hydrogen-bonding effects14, while simulations usually deal with all-atom descriptions15,16. More recently, two of us have proposed a semi-grand canonical multi-scale approach to study PNIPAm ...
