Membrane Structure

Membrane's are important because without them there would me no us. Biological membranes are sheetlike structures mostly made from lipids and proteins. Membrane-Lipids are in the bilayer and are 60 to100 Å(angstroms) thick. Protein membranes are spread all around the bilayer and perform the functions of the membrane. Both the lipids and proteins are constantly moving. Lipids are the primary determinants of the main structure, while the proteins carry out the membrane structure. Membranes are found everywhere and there are many different types. The plasma membrane surround cells and cells are what make up living things. The plasma membrane keeps the cells intact by holding all the cellular components inside. and it also protects it by keeping unwanted things outside of the cell. The membrane has may different functions that include signaling to other cells and transmitting the reaction into the cell itself, provides cell to cell contact that give direct communication. Membranes are actually permeable structures. 

The different parts of the membrane are obviously important towards it. The integral protein is a protein molecule that is permanently attached to the biological membrane and are hard to detach from the membrane. The peripheral protein is a protein that temporarily attaches to the membrane and it functions as sort of a communicator. The carbohydrates obviously are the sugars and other energy sources that help keep the membrane strong and functional. So not only did I learn about what the cell membrane does but I also learned about why it is used and a few terms and functions of it.
