Phospholipids and Membrane Structure Ms MacCormack

Function Plasma/Cell Membrane’s function is to maintain homeostasis This is done by controlling what goes in and out of the cell. The plasma membrane is able to do this because of the membrane being selectively permeable.

Fluid Mosaic Model

Phospholipid bilayer = 2 layers of phospholipids

Phospholipid Structure Polar Head ->Hydrophilic Nonpolar Tail -> Hydrophobic

Terms to Know Hydrophobic = water fearing Hydophilic = water loving Polar Head = glycerol + phosphate Hydrophilic Nonpolar Tails = fatty acid tails hydrophobic
