that under certain conditions an atom of hydrogen is attracted by rather strong forces to two atoms, instead of only one, so that it may be considered to be acting as a bond between them.” This implies that there are three atoms forming the hydrogen bond: The (hydrogen) donor D, the ...
hydrogen bondacceptorwhereas the hydrogen attached to a more electronegative atom serves as the hydrogen bonddonor. The proton acceptor is the electronegative atom that is not covalently bound to the hydrogen. The proton donor is the atom covalently bound to the hydrogen. The proton donor is a...

Hydrogen Bond DonorThe synthesis of high molecular weight poly(vinyl ethers) under mild conditions is a significant challenge since cationic polymerizations are highly sensitivity to chain transfer and termination events. We identified a novel and highly effective hydrogen bond donor (HBD)锕恟ganic ...
A hydrogen bond is mainly formed between a donor atoms such as an amine, which acts as a ligand, or a lewis base and acceptor atom like carboxylic acid. The larger the number of amino acids in a given protein molecule, the greater is the probability of the formation of hydrogen bonds. ...

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...
What is a hydrogen bond donor? What is a covalent bond in chemistry? Are hydrogen bonds covalent? Can hydrogen form a double bond? Is a hydrogen bond stronger than a covalent bond? How is a hydrogen bond different from a covalent bond?
Earlier, natural bond order analysis has also been used to provide an energy-based definition of hydrogen-bonding44. Our ALMO-EDA method, however, is also able to divide the total interaction energy into several chemical sensible components corresponding to many-body effects and donor-acceptor ...
