Cholesterol is essential factor in homeostasis. Name 4 uses that human body has for cholesterol?

Answer 1

Homeostasis is the property of an open system, especially living organisms, to regulate its internal environment to maintain a stable, constant condition, by means of multiple dynamic equilibrium adjustments, controlled by interrelated regulation mechanisms
Cholesterol

AHA Scientific Position
Cholesterol is a soft, waxy substance found among the lipids (fats) in the bloodstream and in all your body's cells. It's an important part of a healthy body because it's used to form cell membranes, some hormones and is needed for other functions. But a high level of cholesterol in the blood — hypercholesterolemia — is a major risk factor for coronary heart disease, which leads to heart attack.

Cholesterol and other fats can't dissolve in the blood. They have to be transported to and from the cells by special carriers called lipoproteins. There are several kinds, but the ones to focus on are low-density lipoprotein (LDL) and high-density lipoprotein (HDL).


LDL cholesterol?

Low-density lipoprotein is the major cholesterol carrier in the blood. If too much LDL cholesterol circulates in the blood, it can slowly build up in the walls of the arteries feeding the heart and brain. Together with other substances it can form plaque, a thick, hard deposit that can clog those arteries. This condition is known as atherosclerosis. A clot (thrombus) that forms near this plaque can block the blood flow to part of the heart muscle and cause a heart attack. If a clot blocks the blood flow to part of the brain, a stroke results. A high level of LDL cholesterol (160 mg/dL and above) reflects an increased risk of heart disease. If you have heart disease, your LDL cholesterol should be less than 100 mg/dL. That's why LDL cholesterol is called "bad" cholesterol. Lower levels of LDL cholesterol reflect a lower risk of heart disease.


HDL cholesterol?

About one-third to one-fourth of blood cholesterol is carried by HDL. Medical experts think HDL tends to carry cholesterol away from the arteries and back to the liver, where it's passed from the body. Some experts believe HDL removes excess cholesterol from plaques and thus slows their growth. HDL cholesterol is known as "good" cholesterol because a high HDL level seems to protect against heart attack. The opposite is also true: a low HDL level (less than 40 mg/dL in men; less than 50 mg/dL in women) indicates a greater risk. A low HDL cholesterol level also may raise stroke risk.

Lp(a) cholesterol?

Lp(a) is a genetic variation of plasma LDL. A high level of Lp(a) is an important risk factor for developing atherosclerosis prematurely. How an increased Lp(a) contributes to heart disease isn't clear. The lesions in artery walls contain substances that may interact with Lp(a), leading to the buildup of fatty deposits.


Cholesterol is an essential nutrient for human health that saves lives.

Answer 2

1) synthesis of bile acids 2) how the synthesizes vitamin
3) synthesis of the steroid hormones 4)The human body contains about 100 g of cholesterol. Most of this is incorporated in the membranes from which cells are constructed and is an indispensable component of them

Answer 3

The 4 uses are
1 synthesis of Vitamin D
2 synthesis of bile salts
3 synthesis of sex hormones like testosterone, estrogen
4 for energy since it is a lipid

Answer 4

We need blood cholesterol because the body uses it to:

1.Build the structure of cell membranes

2.Make hormones like oestrogen, testosterone and adrenaline

3.Help your metabolism work efficiently; for example, cholesterol is essential for your body to produce vitamin D

4.Produce bile acids, which help the body digest fat and absorb important nutrients

Answer 5

Cholesterol is needed for cell wall functioning and for the production of hormones, such as estrogen and testosterone. However, the body naturally makes cholesterol in every cell, so there is no absolute dietary need for it.

Answer 6

1 synthesis of Vitamin D
2 synthesis of bile salts
3 synthesis of sex hormones like testosterone, estrogen
4 for energy since it is a lipid

Answer 7

The body uses cholesterol to build cell membranes. It is also used in small quantities to build certain hormones such as steriod and sex hormones.
