(A) The plasma membrane of a cell is a bilayer of glycerophospholipid molecules. (B) A single glycerophospholipid molecule is composed of two major regions: a hydrophilic head (green) and ...

This boundary is not inert. The inclusion of proteins in the phospholipid bilayer makes the membrane a dynamic entity capable of sensing and interacting with the cellular environment. For example ...

However, many proteins bind to membranes without such domains. In such cases, the canonical view is that cationic residues on the protein direct it to negatively charged membranes where hydrophobic ...
