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. And so now, to separate these amino acids in solution from the liposome of interest, all we have to do is undergo some type of purification process. So, for instance, we can use dialysis or gel filtration chromatography to basically separate and isolate those liposomes of interest. And then we can, for example, use those liposomes to basically study the rate at which these amino acids actually leave that cell membrane.
