4. What is Cholesterol
Cholesterol is a waxy, fat-like substance that's found in all the cells in your body. Your body needs some
cholesterol to make hormones, vitamin D, and substances that help you digest foods. ... If you have too much
cholesterol in your blood, it can combine with other substances in the blood to form plaque.
Your liver makes cholesterol for your body.
You also can get cholesterol from the foods you eat. Meat, fish, eggs, butter, cheese, and milk all have
cholesterol in them. Fruits, vegetables, and grains (like oatmeal) don't have any cholesterol.
7. Cholesterol Synthesis
About 80% of total daily cholesterol production occurs in the liver and the intestines; other sites of higher
synthesis rates include adrenal glands, and reproductive organs. Synthesis within the body starts with the
mevalonate pathway where two molecules of acetyl CoA condense to form acetoacetyl-CoA.
Biosynthesis of cholesterol generally takes place in the endoplasmic reticulum of hepatic cells and begins
with acetyl- CoA.
Cholesterol can both be synthesized endogenously and obtained from the diet.
10. Cholesterol Function
Cholesterol is a major component of all cell membranes and is used to make essential molecules
such as hormones, fat-soluble vitamins, and bile acids to help you digest your food.
In our bodies, cholesterol serves three main purposes:
•It aids in the production of sex hormones.
•It's a building block for human tissues.
•It assists in bile production in the liver.
11. Cholesterol is important
•Build the structure of cell membranes.
•Make hormones like oestrogen,
testosterone and adrenal hormones.
•Help your metabolism work efficiently,
for example, cholesterol is essential for
your body to produce vitamin D.
•produce bile acids, which help the
body digest fat and absorb important
nutrients.

13. Normal concentration of Cholesterol
in blood
Total cholesterol levels less than 200 milligrams per deciliter (mg/dL) are considered
desirable for adults. A reading between 200 and 239 mg/dL is considered borderline
high and a reading of 240 mg/dL and above is considered high.

17. THANK YOU——
But before that let me introduce you to one more Scientific fact about
Cholesterol
✓That your body will not absorb cholesterol if you take it from someone else's
plate.
