September 7, 2011 Biology 311C Lecture 6 Draw the lipid bilayer of a cell membrane. If you wanted to increase the fluidity of the membrane, how would you modify its components? You would increase phospholipids that has unsaturated fatty acids. A macromolecule is molecule made up of many subunits of the same type. They are made up of monomers. The sequence of amino acids determines a protein’s three-dimensional structure. A protein’s structure determines its function (many cellular functions) Lysozyme protects us from bacteria and is part of our immune system. Enzymatic proteins: its function is selective acceleration of chemical reactions. An example is digestive enzymes catalyze the hydrolysis of bonds in food molecules. Defense proteins protect against disease. An example is antibodies inactivate and help destroy viruses and bacteria. Storage proteins store amino acids. Examples include casein (the protein of milk). Hormonal proteins help in the coordination of an organism’s activities. (go to blackboard
