Web13 jul. 2024 · In ice, the hydrogen bonds cause the formation of cavities in the ice, lowering the density of the solid. In liquid water, the hydrogen bonds persist, and are transiently formed on a time scale of ~nano seconds, generating small short-lived clusters of "ice" in liquid water. Hydrogen bonds are present over a wide temperature range. Web18 okt. 2024 · Protein hydration is crucial for the stability and molecular recognition of a protein.
