Abstract:
The binding of a ligand L to a specific site on an adsorbent molecule P is usually studied within the lock-and-key model. In this article we argue that the presence of an aqueous solvent may change dramatically the means by which a ligand recognizes its binding site. The main factor, originating from the specific property of water, is the ability of a water molecule to form a hydrogen-bond-bridge between a functional group on L and a functional group on P. This factor will change the criterion for selecting the best binding site.

Chemical Shift: Internal References and Solvent Effects
The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...

Noncovalent Attractions in Biomolecules
Four types of noncovalent interactions are hydrogen bonds, van der Waals forces, ionic bonds, and hydrophobic interactions.
Hydrogen bonding results from the electrostatic attraction of a hydrogen atom covalently bonded to a strong-electronegative atom like oxygen,...

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
