Helps to stiffen the membrane and it helps to regulate the consistency of the membrane in varying temperatures. Less cholesterol in cold and a bit more in heat, this keeps the bilayer fluid in all temperature variances. Some organisms can vary there membrane cholesterol from one temperature to the other, but most are fixed as per the temperature they live in.

Many people think cholesterol is bad because too much cholesterol in your diet can lead to health problems but you obviously need small quantities to make healthy membranes.

What is the Presence of cholesterol molecules in plasma membranes for?
Cholesterol is found in every cell of your body. It is especially abundant in the membranes of these cells, where it helps maintain the integrity of these membranes, and plays a role in facilitating cell signaling-- meaning the ability of your cells to communicate with each other so you function as a human, rather than a pile of cells.
What role do membranes play in prokaryotes?
Prokaryotic cells do not have membrane bound organelles. The membrane controls the movement in and out of the cell.
What is one role the lipids play in the body?
The lipid cholesterol is the unit from which many of the hormones are formed. If you don't get sufficient cholesterol from your diet, your body will manufacture the material itself.
What the role of sds in buffer?
to disrupt cell membranes
Is the plasma membrane's role excretion?
yes.................
What substance is a steroid?
Cholesterol: cholesterol plays an important role in the cell membranes of animals and humans. Various hormones are also created from Cholesterol. I got this answer from GradPoint.

What is the role of cholesterol in membranes?
Cholesterol helps the membrane keep its shape and relative size. Cholesterol also helps with cell signaling which is how cells communicate with each other.
Is there cholesterol in the membrane?
Yes - cell membranes have cholesterol scattered throughout them. Cholesterol plays an important role in maintaining the integrity of the cell membrane, and may also participate in cell signalling.
What role does the plasma membrane play in the immune system?
it smells like chicken

What role does mucous membranes play to keep the body healthly?
It protects against infectious agents such as fungi,bacteria and viruses.
Is cholesteol made up by the body?
Yes, our liver and intestines produce cholesterol and cholesterol can also be found in our cell membranes. According to the handout I got from my 9th grade Biology teacher, cholesterol "plays an important role in buffering the temperature-dependent fluidity of lipid bilayers by stiffening them at warmer temperatures but increasing fluidity at lower temperatures". So basically cholesterol helps maintain body heat.
What role in cholesterol synthesis and fat metabolism?
the smooth endoplasmic reticulum has the role in cholesterol synthesis, fat metabolism, and detoxification of drugs
What is the role of cholesterol in angina?
Diet plays a role in heart attacks.
