Question

Which of the following statements about the lipoproteins given in the introduction are true?

Answer 1

Answer:

f. Lipoproteins can be distinguished by their densities and composition.

Explanation: Lipoproteins are special particles made up of droplets of fats surrounded by a single layer of phospholipid molecules. Phospholipids are molecules of fats which are attached to a phosphorus-containing group. They are distinctive in being amphipathic, which means they have both polar and non-polar ends.

Lipoproteins are complex particles with a central core containing cholesterol esters and triglycerides surrounded by free cholesterol, phospholipids, and apolipoproteins, which facilitate lipoprotein formation and function.

Answer 2

Answer:

Lipoproteins are compounds that help in the movement of fats to certain body cells. The options below are true about the lipoprotein.

a. Lipoprotein densities vary because lipoproteins have different lipid-to-protein ratios.

C.Chylomicrons are the only lipoproteins that exclusively carry dietary lipids. HDL has a high lipid-to-protein ratio.

d. Lipoproteins are complexes of lipids and proteins.

f. Lipoproteins can be distinguished by their densities and composition.
