A
It forms the main structural layer of the membrane, in place of the phospholipids
B
It makes the membrane freely permeable to ions by creating gaps between the phospholipids
C
It buffers fluidity, restraining movement at high temperature and preventing tight packing at low temperature
D
It anchors ribosomes to the cytoplasmic face of the membrane, so that proteins are inserted into the bilayer as they are made
E
It carries the sugar chains of the glycocalyx and takes part in cell-to-cell recognition
