Amphipathic - a molecule that is "water-loving" (i.e., polar) at one end and "water-hating" (i.e., nonpolar) at the other end; helps hold polar and nonpolar molecules together; characteristic of detergents and of the phospholipid molecules in the membranes of living things...

Amphiphilic lipids, in general, and phosphatidyl ethanolamine, in particular, are major constituents of cell membranes. These molecules form a phospholipid bilayer with their hydrophilic (polar) heads facing their aqueous surroundings (e.g., the cytosol) and their hydrophobic tails facing each other...

Water can move freely across the plasma membranes of most cells and will do so when there is a difference in concentration inside and outside. The diffusion of water across a selectively permeable membrane is called osmosis. Based upon the content of water and solute, cells may be placed in...
