what Peter was just talking about that fatty acid makeup and the phospholipids become so crucial because saturated fats are straight they're rugged they don't bend so it gives some structure to a phospholipid if your phospholipids cake contain a lot of saturated you got a strong cell membrane there that's hard to get through but the real reason cells function and interact with the rest of the cells of your body is they signal each other in signaling occurs because something occurs at a certain member of the lipid cell membrane that we're gonna call a lipid RAF which is a specialized collection of special phospholipids with a little bit of free cholesterol intersperse but the structural positioning that a phospholipid takes up if you have several double bonds in that thing if you've ever seen a 3d view of a phospholipid that's got a several double bonds and it takes up an incredible amount of space so it's two legs spread out and you change the structure of the cell membrane and that structure of that area called the lipid rath allow certain cellular proteins to locate there and those are all our receptors that pull things into cells or extrude things out of cells so the fluidity of the membrane is highly highly dependent on the nature of the fatty acids in the fluidity and the ability to shelter or let certain proteins be expressed in that area if I'm an LDL receptor or some immuno receptor there's certain areas of cell memory and I could never locate - because the phospholipids wouldn't allow it but there are other areas
