So we take the aqueous solution of amino acids, we essentially mix them with that phospholipid solution, the phospholipids that we want to use to form that Bilay, and then we solicit our solution. So this is basically what takes place. We have the individual amino acids shown in purple. We have these individual phospholipid molecules, which, as a result of this bombarding of sound waves, basically disperses and allows them to actually form this bilayer membrane, as shown in this particular diagram. And so what happens is some of these amino acids will randomly end up within the internal Aqueous compartments as these liposomes are actually formed, as these fossil whippets spontaneously naturally form this bilayer membrane. And other amino acids will end up on the outside portion of that cell membrane.
