What is the role of cholesterol? What is cholesterol

Cholesterol: constitutes a biofilm and is involved in the transport of lipids in the blood.

Cholesterol is also known as cholesterol. A derivative of cyclopentane polyhydrophenanthrene. As early as the 18th century, cholesterol was discovered from gallstones, and in 1816 the chemist Bencher named this lipid substance cholesterol.

Cholesterol is widely found in animals, especially in brain and nerve tissues, and is also high in kidneys, spleen, liver, and bile. Its solubility is similar to that of fat, insoluble in water, soluble in ether, chloroform and other solvents. Cholesterol is an indispensable and important substance in animal tissue cells, which not only participates in the formation of cell membranes, but also is the raw material for the synthesis of bile acids, vitamin D and steroid hormones.

Cholesterol is divided into high-density cholesterol and low-density cholesterol, the former has a protective effect on the cardiovascular system, usually called "good cholesterol", and the latter is high, the risk of coronary heart disease will increase, usually called "bad cholesterol". Blood cholesterol levels range from 140,199 milligrams per unit to a relatively normal cholesterol level.

Cholesterol is made up of a retained body part and a long side chain. The total amount of cholesterol in the human body accounts for about 10 mg of body weight, bone contains about 10 mg, skeletal muscle contains about 100 mg, internal organs are mostly between 150 and 250 mg, and liver and ** content is slightly higher, about 300 mg. The highest content is in brain and nerve tissue, containing about 2 grams per 100 grams of tissue, and its total amount accounts for about 4 of the total body total.

There is a large amount of cholesterol inserted between the membrane phospholipids in the eukaryotic cell membrane, which can strengthen the stability of the membrane lipid bilayer, increase the order of the membrane lipid and reduce its fluidity, and regulate the mechanical properties of the membrane.

Cholesterol is a derivative of cyclopentane polyhydrophenanthrene and is a normal component of the human body.

Cholesterol is widely found in animals, especially in nerve tissue and brain, and the content of cholesterol in kidneys, spleen, liver and ** will be relatively high, which is an indispensable substance for animal tissue cells.

Cholesterol is also a normal component of the human body, and participates in the metabolism of various substances in the body, including sugars, proteins, fats, water, electrolytes and minerals, etc., and is very important for maintaining the normal physiological functions of the human body.

Cholesterol mainly comes from the body's own synthesis, and some of it is obtained from the diet. If the cholesterol content of the human body is in the right situation, it can play a protective role in the body. If the cholesterol in the human body is too high, it may have a certain impact on the arterial wall, which will cause plaque formation, inflammatory reactions, etc., and can lead to myocardial infarction, cerebral infarction and other diseases.

Therefore, cholesterol must be controlled within an appropriate range to meet the needs of the human body to avoid the adverse effects of high cholesterol on the body. If there is an abnormality in cholesterol, you should see a doctor in time and standardize the diagnosis and treatment under the guidance of a professional doctor.

You need to pay attention to the problem of high blood pressure.

1. The cholesterol in ** can be converted into vitamin D when it receives ultraviolet rays from sunlight.

2. Cholesterol can help the metabolism of carbohydrates (when the digestion of carbohydrates is clear, the production of cholesterol is also more).

3. Cholesterol plays an important role in the secretion of adrenocortical hormones (such as cortisone) and sex hormones, which are necessary for life.

4. Cholestatic refers to the triver of sail alcohol as an element that constitutes various membranes and produces male and female hormones.

Cholesterol acts differently depending on the type of lipoprotein that goes with it, and lipoproteins are the building blocks of blood that transport cholesterol.
