Some useful animations on the basic structure of the cell membrane by Wisc-Online.
There of course good old wiki.
Membrane science is still an important research area in biology and medicine. This interface between the cell’s interior and its environment is crucial in many aspects of biology. One key discovery is that of aquaporin by Peter Angre in 2003. This discovery won him the Nobel prize in Chemistry together with Roderick Mckinnon, who worked on the structure and mechanism of potassium channels.
