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

Can snakevenom lyse cell membrane?

Can snakevenom lyse cell membrane?

Yes: There's a variety of different toxins secreted by the salivary glands of venomous snakes. Depending on the species, some venoms attack nerves(neurotoxins), heart muscle(cardio toxins), blood cells (hemotoxins), cell membranes (phospholipases). The latter would cause lysis of cell membranes. ...Read more

I read viruses can steal the cell membrane of a cell after it kills it to blend in and not be detected by your body. How does your body then find it?

I read viruses can steal the cell membrane of a cell after it kills it to blend in and not be detected by your body. How does your body then find it?

Temporary housing: A virus does move into a cell and take over its little factory sites to make new virus (not hide). After its presence has destroyed the integrity of that host cell, the cell wall breaks down and all the new viruses enter the blood to find new cells and start over. Your immune system (and fever response) detect the new viruses and work to kill them off.This is considered why your temp fluctuates ...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
