The former interaction energies were always significantly weaker than the latter energies, when the same geometries of the H‐bond donors and acceptors were applied. The chemical origin of this phenomenon was investigated by analyzing the differences among the electronic structures of the local peptide...
By examining the pattern of hydrogen bond acceptors and donors, it is often possible to assign the N and O atoms of glutamine and asparagine side chains. View chapter Related terms: Binding Site Spine Amino Terminal Sequence Beta Sheet IC50 Solution and Solubility Surface Property Conformation ...
and 1088 donor fragments containing one or two possible donor sites. The acceptors were therefore more abundant and chemically more diverse than the donors, which was to be expected under our conditions since there were a lot of heterocyclic compounds in the original...

Carboxylic acids act as both hydrogen bond acceptors and donors. Due to the presence of the carbonyl group, it acts as a hydrogen bond acceptor. The presence of the hydroxyl group makes it hydrogen bond donors. This helps them to participate in hydrogen bonding. Carboxylic acids usually exist ...
Alternatively, why do hydrogen bond donors and acceptors not always pair in descending order of strength? (4) How important is cooperativity for weak hydrogen bonds? (5) Are C-H‚‚‚O hydrogen bonds responsible for crystal packing, or are they the forced consequences of packing? ...

The acidity and basicity as hydrogen bond donors and acceptors have been measured for the compounds Ph 3MOH, where M = C, Si, Ge, Sn and Pb. The trends in acidity and basicity in these compounds indicate that dative pi-bonding from oxygen to M is strong in Ph 3SiOH, weaker in Ph ...
