Explain the relationship among chylomicrons, cholesterol, and the lipoproteins LDL. What is the role of this lipoprotein in the body? Why is it considered “bad”? Where does it come from? Where could it end up?

Expert Solution

Chylomicrons are ultra low-density lipoproteins (ULDL), that consist of triglycerides ,cholesterol, phospholipids and proteins .

Chylomicrons are made in Intestinal Cells.

LDL consists of more amount cholesterol than triglycerides and protein,They are formed in the Liver.

Chylomicrons transport Triglycerides(Fat)[Cholesterol is a type of lipid] from intestine -------- Liver,Skeletal muscle and Adipose tissue.where as,LDL carry cholesterol carries cholesterol from the liver ---------- bloodstream.

LDL are called Bad Cholesterol because,They carry cholestrol synthesized in the liver into BLood stream--------Build up of cholesterol in Arteries----- They stick to Blood vessels----predisposes to Diseases like Atherosclerosis,Myocardial Infarction etc.

LDL are formed in the liver , when triglycerides are removed from VLDL by the lipoprotein lipase enzyme (fewer fat molecules with same protein transport shell), containing a higher proportion of cholesterol esters.They carry CHolesterol into Blood stream and Ends in the Arteries.

10)Two types of cholesterol transport proteins, low-density lipoproteins (LDL) and high-density lipoproteins (HDL), bind to cholesterol and carry it through the bloodstream. Familial hypercholesterolemia (FH) is characterized by high cholesterol levels in the blood, which can lead to cardiovascular disease. FH is associated with a loss-of-function mutation of a gene that encodes LDL receptors in liver cells. Individuals who are heterozygous produce lower-than-normal amounts of the LDL receptors, and individuals who are homozygous for the mutant allele have no LDL...
