Protein hydration shell
WebAug 5, 2009 · Protein surface hydration is fundamental to its structural stability and flexibility, and water-protein fluctuations are essential to biological function. Here, we report a systematic global mapping of water motions in the hydration layer around a model protein of apomyoglobin in both native and molten globule states. WebThe water-holding capacity (WHC) is among the key factors in determining the quality of meat and its value, which is strongly influenced by the content and quality of the connective tissue proteins like collagen. Therefore, the factors that influence the proteins’ stability, e.g., pH, ionic strength, and the antioxidants which are used to increase the meat …

WebAug 15, 2024 · As we can see, protein significantly promotes the formation of a fully H-bonded first coordination shell (Δ n = 0) by ∼40% and depletes the coordination shell with non-H-bonded neighbors, compared to bulk water. This result indicates that protein promotes the water H-bond structure in its hydration shell. WebDec 26, 2007 · The 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.
