How does cholesterol affect our cell membrane fluidity?

How does cholesterol affect our cell membrane fluidity?

It's complicated: Cholesterol stabilizes membranes and keeps them from melting / breaking down at both high and low temperatures but by different mechanisms. This is some serious physical chemistry. Ignore all the "pop" accounts you'll find online and ask a teacher at a good junior college. ...Read more

Are there a large number of cholesterol molecules in the plasma membrane of a single human red blood cell or merely a few?

Are there a large number of cholesterol molecules in the plasma membrane of a single human red blood cell or merely a few?

Large number: Cholesterol molecules are found in every cell of the body, and are especially abundant in cell plasma membranes. The plasma membrane is a continuous double-layer of phospholipids, interwoven with cholesterol molecules and proteins. So, cholesterol molecules are found in great numbers in the plasma membranes of red blood cells. ...Read more

Are cholesterol molecules located in the plasma membrane of human red blood cells?

Are cholesterol molecules located in the plasma membrane of human red blood cells?

Yes: There is a mixture of proteins, phospholipids, and cholesterol in the cellular membrane of red blood cells. This allows the red cells to maintain their flexibility so they can squeeze through small blood vessels. ...Read more

What happens to the plasma membrane of the red blood cells of humans with liver disease to cause the formation of acanthocytes? Thank you.

What happens to the plasma membrane of the red blood cells of humans with liver disease to cause the formation of acanthocytes? Thank you.

Change in lipids: The liver is responsible for general metabolism in the body, and the plasma membrane has a complex collection of lipids that are responsible for its "fluidity" and shape. It is believed that the apolipoproteins are abnormal in liver disease and cause fragility of the rbc membrane causing fragmentation and formation of acanthocytes.

What is a genetic disease that prevents the phospholipids in the plasma membrane of the white blood cells?

What is a genetic disease that prevents the phospholipids in the plasma membrane of the white blood cells?

Unusual: Not sure if i understand the question. There is a disorder called scott syndrome where phospholipids are abnormally oriented in the cell membranes. This prevents activation of the cell. The typical manifestation of this is bleeding disorder, due to the inability of platelets to become activated. ...Read more
