Average number of hydrogen bondsa (H-bonds) and charge pairsb formed by steroids with the surrounding lipids and water.Maarit, Neuvonen
Liquid water's high boiling point is due to the high number of hydrogen bonds each molecule can have relative to its low molecular mass. Water is unique because its oxygen atom has two lone pairs and two hydrogen atoms, meaning that the total number of bonds of a water molecule is four....
The introduction of fluorine atoms in the vicinity of functional groups is one of the ways this can be achieved. In this chapter, a number of hydrogen-bond acidity scales are reviewed, with a focus on the hydrogen-bond donating capacity of alcohols. An overview of experimental data showing ...
Output: • -num: number of hydrogen bonds as a function of time. • -ac: average over all autocorrelations of the existence functions (either 0 or 1) of all hydrogen bonds. • -dist: distance distribution of all hydrogen bonds. • -ang: angle distribution of all hydrogen bonds. ...
number of amino acids in a givenprotein molecule, the greater is the probability of the formation of hydrogen bonds. These interactions significantly contribute to conformational energy. The major ways in which the chains fold to bring interacting groups together are primarily of four different types...
D Kajiya,K Nishikawa,Ken-ichi Saitow - 《Journal of Physical Chemistry A》 被引量: 34发表: 2005年 Fluctuation theory of hydrogen bonding in near-critical fluids Recent experiments indicate that the number of hydrogen bonds in solutions increases in the critical region of the solvent. This effect...
Furthermore, density functional theory (DFT) calculations of the same parameters were performed for a model spin label with the possibility to vary the dielectric constant (ε) of the medium and the number of hydrogen bonds formed with the nitroxide oxygen. From a qualitative analysis of ...
offers a synthesis of what is known and currently being researched on the topic of hydrogen bonds and water molecules. The most simple water molecular, H2O, is a fascinating but poorly understood molecule. Its unique ability to attract an exceptionally large number of hydrogen bonds induces the ...
The total number of hydrogen bonds formed between water molecules is 4. Each water molecule can form 2 hydrogen bonds between oxygen and the two hydrogen atoms in the molecule. An additional two bonds can be formed between each hydrogen atom and nearby oxygen atoms. A consequence of hydrogen b...
The hydrogen bond is the most important of all directional intermolecular interactions. It is operative in determining molecular conformation, molecular aggregation, and the function of a vast number of chemical systems ranging from inorganic to biological. Research into hydrogen bonds experienced a stagna...
