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. ...
Supramolecular polymerization of donor鈥恆cceptor type molecules leads to mixed or self鈥恠orted assemblies depending on the donor鈥恆cceptor strength and extent of noncovalent interactions between the components. Herein, we discuss how competing hydrogen bonding motifs control the supramolecular ...
Intermolecular hydrogen bonding is an attractive interaction that occurs between two or more molecules for which each molecule has one or more hydrogen bond donor sites or one or more hydrogen bond acceptor sites.

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. ...
The doubly hydrated MSA (MSA⋅(H2O)2) has two H-bond between MSA and H2O. The first H-bond is the one between MSA donor and H2O acceptor with a bond length of 1.843 Å, while the second H-bond is between H2O donor and MSA acceptor with a bond length of 2.226 Å (Fig. 2b...
Hydrogen-Bond Donors in Drug Design 榴莲是西瓜味的 不舍爱与自由 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...
Now you know how and why hydrogen bonds form and how to identify donor and acceptor atoms within a hydrogen bond. Did you find this article helpful? Let us know in the comments section below. Or check out more articles in ourChemistry for Biologistschannel. ...
Carbon dioxide capture data for an isolated hydrogen bond donor and hydrogen bond acceptor, as well as natural deep eutectic solvents, were collected. In addition to experimental data, a theoretical study using Density Functional Theory was carried out to analyze the properties of these fluids from...
The hydrogen bond is a dipole-dipole bonding interaction between a hydrogen atom, which is covalently bonded to an electronegative atom (donor), and another electronegative atom (acceptor) [117]. The donor and acceptor atoms are normally oxygen, nitrogen or fluorine. The bond energy for a hydrog...
