Structure of cell membrane pdf
WebJul 30, 2024 · The plasma membrane is composed of a bilayer of phospholipids, with their hydrophobic, fatty acid tails in contact with each other. The landscape of the membrane is studded with proteins, some of which span the membrane. Some of these proteins serve to transport materials into or out of the cell. http://www.pc.maricopa.edu/Biology/amarti-subirana/BIO%20241/Adobe%20PDF%20Files/Membrane%20Structure%20and%20Function.pdf
