Computer Simulations of Lipids


Cells are surrounded by membranes, thin sheets made up of two layers of molecules that separate the inside from the cell from its environment. These molecules, lipids, have water-loving headgroups and oily tails, so that the membrane has an oil-like interior. Biological membranes contain a vast variety of proteins that are responsible for contact between the cell and the outside world: they transmit signals, transport nutrients and other molecules, and maintain the right conditions for the cell. Lipids also play an important role in these processes
