Cholesterol is also known as cholesterol.A derivative of cyclopentane polyhydrophenanthrene.Cholesterol was discovered in gallstone as early as the 18th century. In 1816, chemist benschel named this lipid substance cholesterol.Cholesterol is widely found in animals, especially in the brain and nerve tissues. It is also found in the kidneys, spleen, skin, liver and bile.Its solubility and fat similar, insoluble in water, soluble in ether, chloroform and other solvents.Cholesterol is an essential substance in animal tissues. It is not only involved in the formation of cell membranes, but also the raw material for the synthesis of bile acids, vitamin D and steroid hormones.Cholesterol can also be metabolized into bile acids, steroid hormones, 7-dehydrocholesterol, and 7-dehydrocholesterol is converted to vitamin D3 by ultraviolet light, so cholesterol is not harmful to the human body.

Function
Formation of bile acid
Bile is produced in the liver and stored in the gallbladder, where it is released into the small intestine to be mixed with digested fat.The function of bile is to convert large particles of fat into small particles, making them easy to interact with enzymes in the small intestine.In the tail of the small intestine, 85 to 95 percent of bile is reabsorbed into the blood, the liver reabsorbs cholic acid to keep it circulating, and the remaining bile (5 to 15 percent) is excreted in the feces.The liver needs to produce new cholic acid to make up for the 5 to 15 percent loss of cholesterol.[3]
Form cell membrane
Cholesterol is an important component of cell membrane, which is surrounded by every cell in human body. Cholesterol is its basic component, accounting for more than 20% of plasma membrane lipids.It has been found that when animals are fed a diet that is low in cholesterol, their red blood cells become brittle and easily rupture.Studies have shown that cholesterol prevents the disorder of bilayer at high temperature.When the temperature is low, it can interfere with the formation of liquid crystal and maintain its liquidity.Therefore, it is conceivable that without cholesterol, cells would not be able to function properly and their lives would be terminated.
Synthetic hormones
Hormones are chemical messengers that coordinate the metabolism of different cells in a multicellular body. They are involved in the metabolism of various substances in the body, including sugars, proteins, fats, water, electrolytes and minerals.Hormones such as cortisol, aldosterone, testosterone, estradiol and vitamin D released by the adrenocortical and gonadal glands of the human body are steroid hormones, and the precursor is cholesterol.
It is an important raw material for manufacturing hormones and can be used as emulsifier
Cholesterol has a wide range of physiological functions in the body, but when its excessive will lead to hypercholesterolemia, adverse effects on the body.Modern studies have found that atherosclerosis, venous thrombosis and cholelithiasis are closely related to hypercholesterolemia.If it is simply high cholesterol, dietary regulation is the best approach. If it is accompanied by high blood pressure, it is better to monitor blood pressure as long as it is determined by the doctor as high blood pressure, and then use antihypertensive drugs.Hypercholesterolemia is an important cause of atherosclerosis, so be aware of it.
Cholesterol in nature mainly exists in animal food, a few plants have cholesterol, most plants have structure and cholesterol very similar substances - plant sterols.Plant sterols do not contribute to atherosclerosis.In the intestinal mucosa, plant sterols (especially valley sterols) competitively inhibit cholesterol absorption.
