are eas i ly dis solved in lip ids and thus can move back and

solve in fat, such as car bon diox ide and alco hol, can eas -

Although the water mol e cule is insol u ble in fat, because
of its small size and elec tri cal charge, it eas i ly pass es
through the cell mem brane. The phys i cist and biol o gist
Professor Gerald Schroeder describes the impor tance of
this spe cial char ac ter is tic of the cell mem brane:

Though high ly flex i ble, the tenac i ty of the bonds between the
phos phol i pids mol e cu les main tains struc ture. Pinch some
skin. It doesn't break or crack. Release it, and it returns to the
orig i nal shape. Puncture a cell mem brane with an ultra-sharp
nee dle and then with draw the nee dle. The mem brane res eals
the hole and goes on with its work. Because the mem brane has

The cell membrane is permeable to oxygen, fats and small molecules bear-
ing no electrical charge. It is impermeable to electrically charged or polar-
ized large molecules such as ions or protein. That a layer made up of fat—
the cell membrane—possesses such a sensitive selection mechanism is
just one example of the infinite wisdom of Allah.
