Cholesterol can be both good and bad.It depends on which type of cholesterol is high or low.
Low-density lipoprotein (or LDL)
very-low-density lipoprotein (VLDL)
high-density lipoproteins (HDL). It makes steroids.

Cholesterol molecules in the Plasma Membrane (Cell Surface Membrane) of any cell, help in maintaining the fluidity of the membrane.
The more the cholesterol molecules, the less fluid is the membrane ...and the more rigid it is.
Cholesterol in the blood, might help "Atheroma" (fat deposits in the arteries) to form, and so blocks the artery partially and suppresses the flow of blood through it .
This is so dangerous, because if this happens in the coronary artery, it will suppress the oxygen supply to the heart muscles, and the person will get a coronary heart attack/disease.

What is the difference between satuarated fat and unsatuarated fAT?
While both unsaturated fat and saturated fat are in a variety of foods, studies have found that these fats are not created equally. Unsaturated fats can be beneficial to your heart, whereas saturated fats could be detrimental to your cholesterol and your heart.Saturated fats are found in animal products and processed foods, such as meats, dairy products, chips, and pastries. The chemical structure of a saturated fat is fully saturated with hydrogen atoms, and does not contain double bonds between carbon atoms. Saturated fats are not heart healthy, since they are most known for raising your LDL cholesterol ("bad" cholesterol).Unsaturated fats, on the other hand, are found foods such as nuts, avocados, and olives. They are liquid at room temperature and differ from saturated fats in that their chemical structure contains double bonds. Additionally, studies have shown that unsaturated fats are also heart-healthy fats - they have the ability to lower LDL cholesterol and raise HDL cholesterol ("good" cholesterol).So, if you are trying to follow a cholesterol-lowering diet, eating unsaturated fats should not raise your cholesterol levels further. However, you should try to avoid foods high in saturated fats, since consuming a diet high in this type of fat could increase your risk of having high cholesterol and heart disease over time.

How cholesterol resists changes in membrane fluidity with temperature change?
Adding Cholesterol to a cell membrane reduces fluidity, therefore, making the cell membrane more rigid reducing phospholipid movement. For example, fishes that live in colder waters tend to have less cholesterol content which hinders solidification by disrupting the regular packing of phospholipids. The reason is that in colder waters, they need to have a fluid cell membrane otherwise they would freeze to death. On the other hand, a tropical fish needs to maintain a certain level of rigidity due to the temperature which tends to be warmer in tropical waters, so increasing their cholesterol in cell membranes makes their cell walls more resistant to the heat and denaturing.Because of the way cholesterol is shaped, part of the steroid ring (the four hydrocarbon rings in between the hydroxyl group and the hydrocarbon "tail") is closely attracted to part of the fatty acid chain on the nearest phospholipid. This helps slightly immobilize the outer surface of the membrane and make it less soluble to very small water-soluble molecules that could otherwise pass through more easily.4Without cholesterol, cell membranes would be too fluid, not firm enough, and too permeable to some molecules. In other words, it keeps the membrane from turning to mush.While cholesterol adds firmness and integrity to the plasma membrane and prevents it from becoming overly fluid, it also helps maintain its fluidity.At the high concentrations it is found in our cell's plasma membranes (close to 50 percent, molecule for molecule) cholesterol helps separate the phospholipids so that the fatty acid chains can't come together and cyrstallize.5Therefore, cholesterol helps prevent extremes-- whether too fluid, or too firm-- in the consistency of the cell membrane.
What are scientifical proven causes of a stroke?
Blockage of blood vessels (local or distal), and bleeding (tear of vessel). So: hypertension, cholesterol, cardiac arrhythmias, and trauma.
What is the difference between 'no cholesterol' and 'cholesterol free'?
Something with no cholesterol has no cholesterol in it; something that is cholesterol free can either be free of cholesterol (and thus has no cholesterol - see above) or it has free cholesterol, in which case the level of cholesterol is indeterminate without further information.
