Question

Cell membrane is a phospholipid bilayer. Within the cell membrane, cholesterol
with other phospholipids cluster as microdomains known as lipid rafts. These
aggregates are sites for signalling across the plasma membrane. Given below is the
structure of cholesterol. In this system how cholesterol can act as a dynamic glue
that hold the rafts together?

Answer 1

Answer:

The plasma membranes of cells contain combinations of glycosphingolipids, cholesterol and protein receptors organised in glycolipoprotein lipid microdomains termed lipid rafts. ... Lipid rafts are more ordered and tightly packed than the surrounding bilayer, but float freely within the membrane bilayer.
