what is the different between cholesterol, HDL and LDL?
when we go for blood test check, we see the cholesterol, HDL = (good fat) and LDL = (bad fat) I would like to know exactly what are the differences between these 3 catogories or types of fat?
are HDL and LDL type cholesterol as well? what is the function of each of them or come from what? and how to increase or reduce each of them? and what are the risk levels of each of them when higher or lower the optimal range? I will appreciate any advices..
many thanks in adavnce,
This is an incredibly detailed and long explanation. I’ll try to cover the surface and find you some links.
HDL and LDL aren’t cholesterol (C) themselves, think of them as cholesterol carrying "bottles". The third fat on you saw on your blood test was probably triglyceride (TG).
The different between HDL and LDL is simply how much "cholesterol ester"(CE) it has (it’s actually much more complicated than that but let’s keep it simple). CE are safer for the body since it doesn’t damage things that it touches and HDL has more of it. While LDL has more C, which can damage other cells it touches.
The other issue is that LDL has marker on it’s surface called APO-B100… this marker can get damaged easily by toxin. Once the marker is damaged the LDL can never come back to liver again. So now it is forced to roam around in the blood until it eventually dies and gives us a atherosclerosis. HDL can save the day by finding these dead and collecting the C from them before they cause any problems and returning it back to the liver.
TG are like storage forms of fat. It’s what you think of when you talk about fat around the waist.
This was a really vague explanation. But I think I probably already lost most people, so saying more would be to no avail.
Hope that made sense, if you still have more specific questions drop me a message and i’ll try to help.

Low Density Lipoprotein (LDL) carry cholesterol, triglycerides, and other fats, called lipids, in the blood to various parts of the body.
It is hypothesized that HDL can remove cholesterol from atheroma within arteries and transport it back to the liver for excretion or re-utilization, which is the main reason why HDL-bound cholesterol is sometimes called "good cholesterol", or HDL-C.
Formula: Serum cholesterol–HDL = (serum triglyceride / 5) + LDL.

Cholesterol is a type of fat. There are two main sources for your body cholesterol: 1- your body synthesis 2- food you eat.
Since it is a fat, cannot be dissolved in blood, thus it needs some "carries". Here enters the role of HDL and LDL, they both are lipoproteins, which do carry (transport) cholesterol in your bloodstream.
HDL transports mainly from blood to liver (thus washing cholesterol out of your bloodstream), that’s why it is called "good" cholesterol.
LDL transports it to and from your body cells, and has more probabilities to attach to your blood vessels walls (forming atherosclerotic plaques, thus leading to vessel blockage, and related symptoms). That’s why it is called "bad" cholesterol.
The total cholesterol, is the sum up of HDL and LDL.
There are various ways to lower LDL and increase HDL levels. Find out some http://www.cholesterol-hdl-ldl.com/what-is-ldl-cholesterol.html

All I know id that one has a higher density (HDL, high density lipid, or fat)), and the other is Low density fat.
The one that we have problems with is the High density – I believe – because it sticks against the vein walls, obstructing it.
This criteria is debated as we speak, saying that "cholesterol is a protection of the area affected" and that is the reason why it being there.

Hi Momtaz_Bkk,
HDL and LDL refer to "packages" produced by the liver. When you consume a food high in cholesterol or fat the liver packages the fat and cholesterol into HDL and LDL to transport through your system. LDL (low density lipoprotein) contains more cholesterol and triglycerides (fat) while HDL contains higher levels of protein. HDL will pick up cholesterol deposited along artery walls – one of the benefits.
All the best,
