Document Summary

Turn tails upward and heads face the water. Going from outside to in and inside to outside after adding protein. Form a new bond called a ester bond. Can do three times for each fatty acid. Carbon linked to a ester bond linked to a fatty acid. Can change characteristics so second fatty acid group is hydrophobic. Sprinkle phospholipids onto the surface of the water. Will orient with respect to the dipole moments. Doesn"t tell how we form a biological membrane. Individual head groups will turn around and face the water with the tails pointing inward. One water slides in and breaks the whole thing apart. Need to create a thermodynamically stable structure in water. Orient phosphate with another layer inside with tails facing and heads are opposite each other. Will form a well where it will be a stable structure with water in the center and surrounding the outside. Plane of bilayer that extends for long distances.
