Hydration shell around proteins
WebWater structures in hydration shells of biomolecules are difficult to study in situ due to ... Experiments and computation show that vibrational chiral sum frequency generation … The hydration shell (also sometimes called hydration layer) that forms around proteins is of particular importance in biochemistry. This interaction of the protein surface with the surrounding water is often referred to as protein hydration and is fundamental to the activity of the protein. The hydration layer around a protein has been found to have dynamics distinct from the bulk water to a distance of 1 nm. The duration of contact of a specific water molecule with the protein surface …

WebThe focus in protein folding has been very much on the protein backbone and sidechains. However, hydration waters make comparable contributions to the structure and energy of proteins. The coupling between fast hydration dynamics and protein dynamics is considered to play an important role in protein folding. Fundamental questions of … WebThe hydration shell is generally characterized in a troubling light: it comprises all those water molecules which have a significant effect on their characteristics (e.g. their dynamics). Such...
