What is the difference between LDL and VLDL?

Looked at my mom's cholesterol test results and couldn't figure out the difference between LDL and VLDL. Any information is much appreciated.

Low-density lipoprotein (LDL) is a class of lipoprotein particles that varies in size (18-25 nm in diameter) and contents (while carrying fatty acid molecules in blood and around the body). It is the final stage of VLDL (very low-density lipoprotein) which is produced by the liver. The LDL contains the apolipoproteins B-100 (Apo B-100, a protein with 4536 amino acid residues) and Apo E.[1] It also contains antioxidative vitamins (vitamin E or carotinoids). It is commonly referred to as bad cholesterol as high LDL levels can lead to cardiovascular disease. Generally, LDL transports cholesterol and triglycerides from the liver and small intestine to cells and tissues which are taking up cholesterol and triglycerides.

Very Low Density Lipoprotein (VLDL) is a lipoprotein subclass. It is assembled in the liver from cholesterol and apolipoproteins. It is converted in the bloodstream to low density lipoprotein (LDL). VLDL particles have a diameter of 30-80 nm. VLDL transports endogenous products where chylomicrons transport exogenous (dietary) products. VLDL transports endogenous triglycerides, phospholipids, cholesterol and cholesteryl esters. It functions as the body's internal transport mechanism for lipids.*

LDL=Low Density Lipids
VLDL=Very Low Density Lipids

Both are in reference to cholesterol

high density lipoprotein -
low density lipoprotein
very low density lipoprotein
There is an easy way to remember it - -
H = healthy cholesterol
L = lethal cholesterol
and yes,
VL = very lethal cholesterol

No one has answered the question you're really asking.
VLDL and LDL differ in size, density and lipid composition. VLDL are one of the largest, most bouyant particles and have a high concentration of TG (triglycerides). LDL by contrast have more cholesterol ester and carry the majority of cholesterol in the blood.

Trigylcerides and cholesterol are both necessary for life -- in the right amounts. High levels of LDL cholesterol are associated with atherosclerosis and resultant complications. High levels of VLDL TG appear to decrease good HDL cholesterol levels and are a significant factor in heart disease.

the difference is on molecular weight:
LDL= low density lipoproteins
VLDL= very low density lipoproteins
HDL= high density lipoproteins
HDL is named good cholesterol
LDL is the bad colesterol
in fact, for your lipidic status the interest is in knowing total cholesterol and HDL, LDL

LDL is low density lipoprotein and VLDL is Very low density Lipoprotein. LDL is termed as the bad cholesterol and vldl the "very bad" cholesterol. The lower the density the higher the risk of atherosklerosis and consequences, like Myocardial infarction and Stroke. So VLDL is more dangerous than LDL
