Was Sind Lipid Rafts?

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.

What is a lipid raft and what is its function?

Lipid rafts are plasma membrane microdomains enriched in cholesterol and sphingolipids that are involved in the lateral compartmentalization of molecules at the cell surface. Internalization of ligands and receptors by these domains occurs via a process defined as raft-dependent endocytosis.
