LIFE 210 Lecture Notes - Lipid Bilayer, Sphingosine, Cerebroside
Document Summary
Thin (~50 atoms thick, 1/100 th to 1/1000 th thickness of a cell, 10,000 membranes = sheet of paper) Associate such that the nonpolar tails are away from the water. All have a phosphate which then bonds head group. Phosphate has negative charge, so phosphate + head group together is what shows charge of entire head group. Lipid molecules in a membrane can diffuse freely. Review session thursday 5 6 pm path 101. Quizzes and study guide are the pool of questions for the exams. Study guide free response (4 of 5) When a lipid bilayer is torn it does not seal by forming a hemi-micelle cap because membrane lipids are cyclindrical. Five students in this class always sit together in the front row. If analogous to why lipid bilayers form, the reason for this is nobody else in the class wants to sit next to them.
