Document Summary
January 9 and 11 (lecture 1 & 2) Proteins can be visualized using gfp because gfp (aka green fluorescent protein) is a marker protein that is characteristic of a specific organelle/protein. The functions of cell membranes include: signaling (communicating with the outside of the cell and inside, controls passage of materials (plasma membrane which is selectively permeable, receives and transmits information, serves as a partition. Lipids include fats, oils, hormones, and certain components of membranes that are grouped together due to their lack of desire to interact with water. Lipid bilayers form spontaneously because of the hydrophobic effect. Hydrophobic effect: when hydrophobic (non-polar) molecules cluster together, water molecules are released to the system which adds disorder. This disorder is then stabilized via van der waals interactions. Structures of phospholipid: phospholipids form structures to minimize exposure if hydrophobic (water fearing) regions to water. Asymmetry is established after phospholipids are made in the er membrane (flippases)
