In aqueous media, formation of hydrogen bonds between water molecules and oxygen-containing groups on the surface of NPs may weaken heteroaggregation arising from hydrogen bonding [47]. Hydrogen bonds (5–10 kT) are generally stronger than common van der Waals bonds (~ 1 kT) but weaker than ...
The most ubiquitous, and perhaps simplest, example of a hydrogen bond is found betweenwatermolecules. In a discrete water molecule, water has two hydrogen atoms and one oxygen atom. Two molecules of water can form a hydrogen bond between them. The oxygen of one water molecule has two lone p...

(Supplementary Figs.28and29) observed previously for this host30. Instead, the host forms a complex framework held together by N–H…O–S hydrogen bonds combined with water bridging G and S ions by hydrogen bonding, resulting in pockets occupied by the guests. Notably, the two acetyl groups...
(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 ...
environment, side chains of hydrophobic amino acids will cluster in the core of the protein to avoid contact with water, whereas the hydrophilic side chains are exposed on the surface of the protein and are free to form hydrogen bonds with water molecules or other polar amino acid side chains...
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 ...
Those which cannot form hydrogen bonds we can think of as slippery. The scientific name for this is "hydrophobic" which means "water fearing". Examples of slippery molecules are fats and oils. On the other hand molecules which stick to water, such as alcohol and sugar, are called "...
Water is thus one of the very few substances whose solid form has a lower density than the liquid at the freezing point. Localized clusters of hydrogen bonds still remain, however; these are continually breaking and reforming as the thermal motions jiggle and shove the individual molecules. As ...
