You are studying the effects of temperature and lipid composition on membrane fluidity using artificial membranes containing only one or a few kinds of lipids and no proteins. Assume that you and your lab partner have made the following artificial membranes: Membrane 1: Made entirely of phosphatidylethanolamine. Each of the two chains of the fatty acids is 18 carbon in length and both are completely saturated. Membrane 2: Made entirely of phosphatidylethanolamine with 14-carbon fatty acid chains. only one fatty acid tail contains a double bond, the other one is

Question
You are studying the effects of temperature and lipid composition on membrane fluidity using artificial membranes containing only one or a few kinds of lipids and no proteins. Assume that you and your lab partner have made the following artificial membranes: Membrane 1: Made entirely of phosphatidylethanolamine. Each of the two chains of the fatty acids is 18 carbon in length and both are completely saturated. Membrane 2: Made entirely of phosphatidylethanolamine with 14-carbon fatty acid chains. only one fatty acid tail contains a double bond, the other one is completely saturated. Membrane 3: Made entirely of phosphatidylethanolamine with 14-carbon fatty acid chains. Both fatty acid tails have a single double bond. Predict the transition temperature of the above-mentioned membranes.
