My plan is to turn my notes from each lecture into a blog post, figuring out how everything we learned relates to PrP (and maybe huntingtin) along the way. The first class was just review and syllabus, so I’m starting on lecture 2: …

WebbThe Plasma Membrane. Like prokaryotes, eukaryotic cells have a plasma membrane made up of a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment.A phospholipid is a lipid molecule composed of two fatty acid chains, a glycerol backbone, and a phosphate group.
