. The structure of certain porin proteins isorganized into an interesting beta-barrel, in which each beta strand spans the lipidbilayer at an ~45° angle. Using this information, together with general dimensions of thelipid bilayer, what would be the approximate number of amino acids found within a betastrand in an aquaporin protein complex? Explain how you arrive at your answer.

1. The CFTR protein is a chloride channel in the cell membrane. Use your understanding of the biochemical properties/categories of amino acids and how they interact with membrane phospholipids to predict the distribution of charged/polar, and non-polar amino acids within the domains of CFTR listed below. Consider one category to include the charged amino acids and the polar amino acids and the other category to include the non-polar amino acids. For each domain, predict which category of amino acids is likely to be most abundant. Also, explain the rationale behind your prediction.
