Question

Why is the mobility of lipids in liposomes greater than that of lipids in biological membranes?

Answer 1

 

Hi Mary, 

 

Biological membranes are made of phospholipids that impart membrane integrity and structure. In contrast, liposomes are lipid storing vesicles that participate in lipid metabolism along with storage. Therefore, lipid mobility is higher in liposomes. Lipid mobility in membrane would adversely affect membrane structure, integrity and tissue morphology.  intrinsic regulatory mechanisms prevent lipid mobility in membranes and preserve their integrity. 

 

Hope this helps.
