Cell Membrane Poster! Yay!

Poster that is now hanging in the biology classroom. Woohoo!

In biology we made posters. But not just any posters! Posters of cell membranes! From making this poster and labeling all the different parts, I learned some new stuff about cell membranes. Cell membranes are very interesting and there is a lot of  "stuff" that is actually part of a cell membrane. Perhaps my favorite of all are the phospholipids which make up the phospholipid bilayer. They keep everything inside. They create a barrier between the "insides" of the cell, and the environment outside of the cell. There are two parts to a phospholipid. The head is hydrophilic and the tail is hydrophobic. Cholesterol is another component of the cell membrane. It resides inside of the phospholipid bilayer. Cholesterol helps cells to communicate with each other. Receptor and transport proteins are also something I learned about the cell membrane. Transport proteins transport different things throughout the cell. Those "things" are received at the you guessed it! The Receptor proteins! Glycoproteins were another part of all of this that really popped out to me. The glycoproteins play a role in cell to cell interactions. Glycoproteins are proteins that contain Oligosaccharide chains covalently attached to polypeptide sidechains. That concludes a little bit about my cell membrane poster. Hopefully this will be the first blog post of many on cell membranes.
