Welcome to the Phospholipids module!
On the display you will find a cube of water. Water is known as the "universal solvent", but it is also a polar solvent. This is because of the uneven electron distribution in the covalent bonds between the oxygen atoms and the hydrogen atoms. For this reason, water is able to disolve polar solutes.
Throughout this module, you will learn how a membrane, which is comprised of phospholipids and play a very important role in cells, interacts with water.
Use the animation box in the lower right corner of your screen. You may also click within the display window and move your mouse to rotate the system. Scrolling the mouse wheel will zoom in and out. We have highlighted one water molecule in red for you to follow.
Click "Previous frame" or "Next frame" to move a single frame forward or backward in the simulation.
