Explаin, in detаil, the structure оf phоsphоlipids аnd how this structure leads to the plasma membrane structure that we observe. Be sure to include how each part of the phospholipid would interact with fluids and the contribution of these interactions to plasma membrane structure. What does this structure mean for how the inner and outer parts of the plasma membrane interact with fluids? How do parts of integral proteins and peripheral proteins interact with fluids based on this information?
