LDL is responsible for carrying cholesterol to cells that need it. Elevated LDL levels are associated with an increased risk of cardiovascular disease.
What is the function of LDL and HDL?
HDL helps rid your body of excess cholesterol so it’s less likely to end up in your arteries. LDL is called “bad cholesterol” because it takes cholesterol to your arteries, where it may collect in artery walls. Too much cholesterol in your arteries may lead to a buildup of plaque known as atherosclerosis.
What is LDL cholesterol and what is its function in the body?
LDL cholesterol is often called the “bad” cholesterol because it collects in the walls of your blood vessels, raising your chances of health problems like a heart attack or stroke. But cholesterol isn’t all dangerous. Your body needs it to protect its nerves and make healthy cells and hormones.

What are the functions of LDL VLDL HDL and chylomicron?
By density
Chylomicrons carry triglycerides (fat) from the intestines to the liver, to skeletal muscle, and to adipose tissue. Very-low-density lipoproteins (VLDL) carry (newly synthesised) triglycerides from the liver to adipose tissue. Intermediate-density lipoproteins (IDL) are intermediate between VLDL and LDL.

Which is better LDL or HDL?
There are two types: high-density lipoprotein (HDL) and low-density lipoprotein (LDL).

The main difference between VLDL and LDL is that they have different percentages of the cholesterol, protein, and triglycerides that make up each lipoprotein. VLDL contains more triglycerides. LDL contains more cholesterol. Triglycerides are a type of fat (lipid) found in the blood.
Which cholesterol is responsible for atherosclerosis?
