Q.

Which of these statements about lipids, is incorrect?

I. Lipids are part of the cell membrane, cell organelles and other biological membranes.

II. Lipids also function as insulators, they add buoyancy to cells and as shock absorbers.

III. High density Lipoproteins (HDL) are harmful lipids, as they are carried by blood easily and get deposited in high pressure vessels as a blocking layer .

IV. Low density Lipoproteins (LDL) are useful lipids carried in form of lipoproteins and help in clearing lipid depositions; they are also used in the formation of hormones.
