interpretation
Hydrophobic interaction occurs through the mutual repulsion between hydrophobic groups of hydrophobic substances and water, and hydrophobic groups are generally non-polar groups. This action makes the hydrophobic groups close to each other, and at the same time makes the water concentrated and more structured.
cage hydrate An image formed by hydrophobic interaction dry ice That way Inclusion compound The "master" substance, i.e. water, forms a cage like structure through hydrogen bonding, which physically traps a "guest" substance, i.e. small hydrophobic molecules. Cage hydrates represent the largest structural response of water to a non-polar substance, similar to Microstructure It also naturally exists in biological substances. Hydrophobic interactions affect most protein The structure and nature of is critical. Hydrophobic interactions provide the main impetus , drain water Residue It is located inside the protein molecule. Interestingly, although most hydrophobic groups of proteins aggregate due to hydrophobic interactions, about 1/3 of hydrophobic groups are still exposed to water, so the special structure of water on the hydrophobic surface exists in the hydration structure of proteins. Lowering the temperature weakens the hydrophobic interaction and strengthens the hydrogen bond. The interaction length of hydrophobic interaction can reach about 100 nm, while other molecules Force Only about 5 nm at most. However, the hydrophobic interaction is so long Operating distance Up to now, scientists have not reached a satisfactory conclusion in their research on the subject.
