How does water interact with proteins
WebFeb 1, 2024 · Hydrophobic interactions in proteins Structure describe the relations between water and hydrophobes (low water-soluble molecules). Hydrophobes are nonpolar molecules and usually have a long chain of carbons that do not interact with water molecules. The mixing of fat and water is a good example of this particular interaction. WebThe channel proteins attach to the cell membrane (hydrophobic region) and provide a hydrophilic passageway for transportation. The polar ions interact with its hydrophilic passageway and pass through it. Why Does Water Need A Channel Protein? Water substances use channel proteins called aquaporins for their Transportation across …
