It also reduces the permeability of the plasma membrane to hydrogen ions (protons) and sodium ions.[2]Cholesterol is essential for the structure and function of invaginated caveolae and clathrin-coated pits, including the caveolae-dependent endocytosis and clathrin-dependent endocytosis.

Cholesterol: Synthesis, Metabolism, Regulation

So many side effects of cholesterol lowering drugs are caused due to their inhibition of proper hormone synthesis from cholesterol. The most common side effects of statin drugs are: loss of physical strength, sexual dysfunction, memory loss, liver dysfunction, changes in mood, myopathy and several other symptoms.

Without cholesterol which in synthesized in the liver, pregnenolone cannot be made. Drugs that inhibit the liver's production of cholesterol may have a very damaging effect upon the cascade of hormones of the endocrine system.

Statins are currently the most powerful cholesterol-lowering drugs available. They act by inhibiting the action of 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase, which is the rate-limiting enzyme in the sequence of steps by which cholesterol is synthesized in the liver. The liver has two sources of cholesterol: it can take up LDL particles from the blood, or it can synthesis cholesterol using HMG-CoA reductase. The diagram below illustrates cholesterol homeostasis in a liver cell. LDL (shown in red) can bind to LDL receptors on the surface of the liver.

This flow chart shows how the synthesis of cholesterol occurs in ..

Binding causes the LDL to be taken up by the liver cell and digested in a lysosome. Fatty acids and amino acids in the LDL are recycled, and the cholesterol enters the cholesterol pool in the liver cell. Note that if the liver cell synthesizes cholesterol, this too will be added to the cholesterol pool. If the concentration of cholesterol in the liver cells exceeds a certain level, HMG CoA reductase is inhibited, and the synthesis of LDL receptors is also inhibited.

Lipid digestion and absorption
Lipids play an important role in cell structure and metabolism. TAGs are the major storage form of energy. Cholesterol is a component of cell membranes and precursor of steroid hormones. Lipid digestion occurs at lipid water interfaces since TAG is insoluble in water and digestive enzymes are water soluble. Lipids are digested and absorbed with the help of bile salts. Products of lipid digestion aggregate to form mixed micelles and are absorbed into the small intestine. Lipids are transported in the form of lipoproteins.

their inhibition of proper hormone synthesis from cholesterol

The mechanism that the present-day cholesterol-loweringdrugs focus on is the NADPH-dependent catalization of HMG-CoA reductasewith HMG-CoA to synthesize mevalonate which is eventually converted toisopentenyl pyrophosphate.
