Virtually all life on earth depends on energy ultimately from: Hydrophobic interactions result from the strong tendency of water to exclude non-polar groups or molecules. Hydrophobic interactions are important in the formation of detergent micelles and the folding of proteins. Hydrophobic interactions result from hydrogen bonds between water and the hydrophobic molecules. The preferential interactions between water molecules exclude hydrophobic substances from aqueous solution and drive the tendency of non-polar molecules to cluster together. Hydrophobic interactions result in non-polar regions of biological molecules being buried in the molecule"s interior to exclude them from the aqueous milieu.
