Phospholipid Bilayer plasma membrane - skin of lipids w/ embedded proteins covering cells protein determines what substances can pass through only 2 phospholipids thick phospholipids - glycerol + 2 fatty acids + phosphorylated alcohol normal fatty acids aren't soluble, nonpolar all over phosopholipids have polar, organic heads forms bilayer sheets so that nonpolar fatty acid tails never touch the water phospholipid bilayer - forms spontaneously due to water's tendency to form the max number of hydrogen bonds stops any water-soluble substances from passing through certain proteins act as passageways through the membrane fluidity of bilayer - phospholipids have weak interactions w/ each other parts of membrane can freely move less fluidity where phospholipid tails align close together some phospholipids don't align well due to double carbon bonds membranes w/ steroid lipids (ex. cholestrol) increase/decrease in fluidity depending on temperature
