Cell Membranes and Membrane Transporta. Living Cell Membranei. Video: Mouse mammary gland tissue collagenb. Preview:i. Components of cell membrane move aroundii. Selective Permeability – only certain molecules can cross the cell membraneiii. Cell Membrane = Plasma MembraneIII. Structure of Cell Membranea. The Fluid Mosaic Model (Fig 5.2)i. Cell membrane is a phospholipid bilayer with proteins inserted through membraneii. Lipids and proteins move aroundiii. Extracellular Layerb. Lipids (Fig 5.5)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.i. All lipids are hydrophobicc. Phospholipidi. Glycerol + 2 Fatty Acids + Phosphate & Cholineii. Joined by an ester linkageiii. Forms by dehydration d. Saturated Fatty Acidi. Hydrocarbon chain has all single bonds1. Carbons are saturated with Hii. Side chains pack tightlyiii. Solid at Room Temperaturee. Unsatruated Fatty Acidi. Side chain has 1 or more double bonds1. Carbons NOT fully saturated with Hii. Double bond causes a kinkiii. Can’t pack tightlyiv. Liquid at Room
