Document Summary
Spring 2009: fatty acids, lipids and membranes, draw the structures of stearate (18:0) and linoleate (18:2) all-cis . Why does stearate have a tm of about 70 whereas linoleate has a much lower tm (less than. What are the two major components of biological membranes: proteins and lipids in membranes are inherently asymmetrical. What is the difference between the paracrystalline and liquid disordered phases of membranes. Explain how a hydropathy plot is generated and what the hydropathy index measures. Draw a topology model of the lac permease in a membrane and indicate the range of amino acids that form each transmembrane -helix. Assume t=298 k and use the values for r and f from your book: describe the structure of serca channel. Include a description of the four domains of the protein (i. e. , the transmembrane domain, the a domain, the n domain and the p domain) and their function.
