Question

Evaluate the various lipoproteins, where are they produced, what do they carry, what apolipoproteins are associated (with their functions) and what is the lipoproteins overall physiological function (include type of lipid transport).

Answer 1

Lipoproteins are the complex biological molecules containing both the lipids as well as protein in their structure, offering the transport for cholesterol in the bloodstream as well as through lymphatic fluid.

These are majorly classified into 4 types:

· Chylomicron

· LDL

· VLDL

· HDL

Where the lipoproteins are formed: The formation occurs majorly in the liver and they are metabolized in the muscles as well as in the adipose tissues through lipase enzyme.

Function of apolipoproteins: these transport lipids as well as oil soluble vitamins in the blood, lymph as well as in cerebrospinal fluid.

Lipoprotein’s major function is in the absorption and transport of the lipids in the liver to the associated peripheral tissues as well as from peripheral tissues to the lives as well as in the intestine.

The role of lipoproteins in lipid transport: They have the significant role in the transport of lipids or fat molecules like cholesterol, triglycerides and phospholipids in the body between the liver and peripheral tissues.
