Physical properties-high heat of vaporization, strong surface tension, high specific heat and nearly universal solvent. If we add oil to water, the hydrophobic effect results in mutual exclusion of oil and water molecules. 2 O Mol. At pH 7.0 a solution is neutral. Biology of molecules- size and shape of molecules, and the nature of weak interactions with other molecules.
Biology is friendly, how do molecules reversibly interact.
The image is from the New Eng. In water, these bonds are very weak. Caused by slight charge displacements. Multiple weak forces can cause strong interactions Biological recognition results from a three dimensional structure that allows multiple weak forces between molecules Intramolecular and intermolecular weak forces are important in biology. The Gecko's feet adhere to any surface by specialized fine hairs called setae, with half a million per foot and each divided into 400-1000 spatulae.
