NOTE - This is a VERY old video. I no longer teach this class and cannot replace it. It is posted ONLY because people asked for me to leave it public. It has several errors in it - including the fact that lipids are not polymers. As with all free resources, students must curate materials for themselves. Please see: https://www.youtube.com/channel/UCMNBQXnBz6F6t2nl-6a5JjQ for my latest videos.
