Explain dipole-dipole interaction, hydrogen bonds, and van der Waals forces. Give examples also. How are ionic and covalent bonds different from hydrogen bonds? How are hydrogen bonds, ionic bonds and covalent bonds different? Why is the bond angle of water greater than hydrogen sulphide? H...
What attracts the atoms in an ionic bond? Which of the following statement is true? A) Dispersion forces are generally stronger than dipole-dipole forces. B) Hydrogen bonds are stronger than covalent bonds. C) Inter-molecular forces hold the atoms in molecules together. D...
Most generally, the hydrogen bond can be viewed as a metric dependent electrostatic scalar field between two or more intermolecular bonds. This is slightly different than the intramolecular bound states of, for example, covalent or ionic bonds; however, hydrogen bonding is generally still a bound ...

Protein–protein interactions, such as hydrogen bonds, electrostatic interactions, hydrophobic contacts, and disulfide-sulfhydryl exchange events follow this [87]. To summarize, heating the albumin solution can cause alterations in the protein's structure and unfold it. Ultimately, this leads to the ...
We hypothesize that the first cluster (aa 47-95) can only stably fold upon the synthesis of the second cluster (approximately aa 450-550), as they are closely interacting, including several hydrogen bonds, despite their distance in the linear sequence (Fig. 4e). Thus, like Trp2, only ...
Thermal gelation is displayed, which comprises the structural alterations and unfolding of proteins generated by heat. Protein–protein interactions, such as hydrogen bonds, electrostatic interactions, hydrophobic contacts, and disulfide-sulfhydryl exchange events follow this [87]. To summarize, heating the...
