Fluid Mosaic Model

The Fluid Mosaic Membrane Molecule models we created in class gave me a good idea of how they are made up and what they look like, obviously.  However, as far as what everything does I'm a little vague on and thus I felt like an utter moron taking the quiz.  The top and bottom layers of the molecule are made up of phospholipids.  Phospholipids. Act as building blocks of the biological cell membranes in virtually all organisms, participate in the transduction of biological signals across the membrane. They also act as efficient store of energy as with triglycerides and play an important role in the transport of fat between gut and liver in mammalian digestion. The little tendrils that are attached to the phospholipids  are fatty acids.  Around the "tails" is cholesterol.  The transmembrane protein is a protein molecule that is attached to, or associated with the membrane of a cell or an organelle.  And finally the glycoproteins are proteins that contain oligosaccharide chains  covalently attached to polypeptide side-chains.  All of these are components in the functions of the fluid mosaic membrane model.
