Lipids and Biomembranes

ID #2394

Can you explain the different types of membranes protein? For example an integral protein, lipid-linked protein, and peripheral protein... etc.


Peripheral membrane proteins are non-covalently and loosely associated with a biomembrane. They can be removed without disrupting the integrity of the membrane. They can interact with other proteins that are embedded in a membrane through Hydrogen bonds or other non-covalent interactions. Integral membrane proteins cannot be removed from a biomembrane without disrupting the membrane. Some integral membrane proteins fully traverse the lipid bilayer and these are known as transmembrane proteins. Membrane-associated proteins (a type of integral protein) are embedded in the lipid bilayer. Lipid-linked proteins are covalently linked to a phospholipid in a biomembrane.
