1,3-Diaminopropane is a polar compound that can form hydrogen bonds. There are unshared electron pairs. Since this unshared electron pair is nucleophilic, its chemical properties are relatively active and it is easy to react with some electrophilic compounds. For example, if it is an organic b...
In a molecule, these are metal-metal bonds. For structures emerging not due to internal bonding, but as a result of external molecular (self-)assembly forces such as dense packing and minimization of the surface energy, we need a different term with an unequivocal everyday life image to ...
Lightweight alcohols are well-known for their antiseptic, stringent, fat, and lipid solvent qualities, while heavier emollients are used for their occlusive, lubricating, and lubricating capabilities. Although some people believe alcohol can dry the skin, it isn’t harmful and has many benefits. ...
Its unique properties and activities come from the presence of intermolecular hydrogen bonds (HBs) with itself and other species. Scientists have been discussing properties other than known bulk water for a long time. However, the particular application of water being researched is limited today. ...
The hydrogen bonding index (HBI) describes the capacity of a solvent molecule to develop hydrogen bonds. Donors have a negative HBI and acceptors a positive HBI. The HBI is determined from the shift of the infrared band for RO-H stretching vibration. For the details, refer to the article by...
A previous study on the mechanism of NaCl-induced reduction in digestibility of myoglobin showed that hydrophobicity and hydrogen bonds played a major role in maintaining the binding between pepsin/trypsin and myoglobin, and the changes of protein conformation (the heme structure and hydrophobic cavity...
the industrial method of producing alcohols, aldehydes, and ketones. Water participates in many chemical processes as a catalyst. For example, the reaction of alkaline metals or hydrogen with halogens, and many oxidation reactions, will not proceed without the presence of small quantities of water....
Small neutral, generally lipophilic molecules are also used such as alcohols or aldehydes but these have the drawback of being toxic for the leucocytes. In fact, reagents containing amines have performance values closer to an ideal lysis process. The lysis reagents containing amines include the am...
It can clearly be seen that one way of attachment contains hydrogen bonds (the strongest interactions in ice) only between the neighboring quasi-layers of water molecules, but not within these quasi-layers (see Figure 4), while another way of attachment contains hydrogen bonds both between and ...
This is supported by the hydrogen bonding data wherein the highest sugar concentrations display the lowest asymptotic number of hydrogen bonds per lipid, suggesting that the lipids are not optimally structured due to the increase solute presence. Diffusion constants for glucose molecules were found to...
