However, a significant amount of bonding stability can be achieved when there is formation of multiple hydrogen bonds between two such systems and elicits a response. Because of the presence of amino acid residues in receptors containing both the hydrogen bond donor and acceptor functionalities, ...
The formation of the DES is attributed to the H-bonding interaction(s) present between the salt and the HB donor. Consequently, addition of a predominantly HB donor or a predominantly HB acceptor cosolvent to such DESs may result in intriguing features and properties. We present investigation of...
The formation of hydrogen bonds at protein-DNA interfaces in aqueous medium involves not only favorable interactions of the donor and acceptor functional groups but also a loss of interactions between these groups with the solvent water. We have investigated the energetics of about 500 potential ...
The unique physicochemical and solvation properties of DESs can be highly tailored by choosing the appropriate hydrogen bond acceptor (HBA) and hydrogen bond donor (HBD). Understanding the role of the HBA and HBD on the multiple solvation interactions in DESs is important to enable their ...
和电负性极强的原子比如氧、氮、氟相连的氢原子可以作为氢键供体,也就是分子中的N-H和O-H。电负性极强的原子比如氧、氮、氟自己是氢键受体。 氢键供体Hydrogen-bond donors被认为比氢键受体hydrogen-bond acceptors给药物设计者带来更多问题。类药物化合物的大部分极性来自于氢键受体,因为它们的数量通常超过了氢键供体...
A chemical bond in which a hydrogen atom that is already bonded to an atom in a molecule forms a second bond with another atom, either in the same molecule or in a different one. The second atom is usually of a type that strongly attracts electrons, such as nitrogen or oxygen. ...

by the experimental reaction Gibbs free energy (ΔG) in the case of 1:1 complex formation when all other intermolecular interactions are small. Scales for hydrogen bond acceptor (HBA) and donor (HBD) strengths can be derived by using a common monofunctional reference donor/acceptor molecule. ...
