Amphipathic(1) Pertains to a molecule containing both polar (water-soluble) and nonpolar (water-soluble) portions in its structure.(2) Of, or relating to, a molecule having hydrophobic and hydrophilic regions.www.biology-online.org
A non-polar molecule is typically not soluble in water because they lack ionic groups capable of water molecule interaction. A term for this type of insolubility is "hydrophobic."
a polar molecule is a molecule such as a lipid that has one part of it attracting something , such as water (hydrophillic) and the other repeling it (hydrophobic)
Water IS a polar molecule.
It ensures that certain key components or activities of a cell are not destroyed when the cell is exposed to water
Probably the most hydrophobic molecule is the cholesterol molecule. It is composed mostly of fat and therefore will move away when exposed to water,
Hydrophobic means that the molecule is repelled by water. You can tell if a molecule is hydrophobic by the way the atoms are arranged.
what happens when they are exposed to water

Urea is a water-soluble compound with a formula of (NH2)2CO , found in urine. Hydrophobic indicates a molecule that is non-polar, and therefore insoluble in water, so Urea is not hydrophobic.

There are two parts to the phospholipid molecule. One is a hydrophobic hydrocarbon chain, which points away from water. The other is a hydrophilic phosphate ionic group, often represented as the "head" of the molecule, which points towards water.
foam is created by small bubbles or mycelles. These are formed by molecules which are hydrophobic (repelled by water) on one end and hydrophilic (attracted by water) on the other. In water, these molecules form a 2 molecule thick layer with the hydrophobic tails on the inside (protected from water) and the hydrophilic ends on the outer side (touching the water). This layer forms the skin/membrane of a bubble. Oil is hydrophobic and disrupts the formation of this 2 molecule thick membrane.
