Cholesterol transfer at the plasma membrane - PubMed
WEBCholesterol homeostasis is of central importance for life. Therefore, cells have developed a divergent set of pathways to meet their cholesterol needs. In this review, we focus on the direct transfer of cholesterol from lipoprotein particles to the cell membrane.
The influence of cholesterol on membrane protein structure, …
WEBSep 1, 2015 · Cholesterol is among the lipid membrane constituents most often observed to be co-crystallized with membrane proteins, and the cholesterol levels in cell membranes have been found to play an essential role in health and disease.
6.3: Structure of the Cell Membrane - Biology LibreTexts
WEBJul 31, 2022 · The amount of cholesterol in animal plasma membranes regulates the fluidity of the membrane and changes based on the temperature of the cell’s environment. In other words, cholesterol acts as antifreeze in the cell membrane and is more abundant in animals that live in cold climates.
