High everyone,
With reagard to lipids, etc and water:
According to wiki, the hydrophobicity of molecules is actually only a product of hydrophilicity; so, rather than polar molecules actually repelling the non-polar molecules, its simply the preference for polar molecules that drives the process, and causes the non-polar molecules to appear to be repelled. A textbook I have doesn;t say this, although it doesn't say anything to the contrary, can someone clarify if wiki is telling me the truth?!
