Question

Lipids are present in acid insoluble fraction. The reason is
(A) Their molecular weight is low
(B) Arranged into structures like cell membrane
(C) The fatty acids are mostly non polar
(D) They are generally water soluble.​

Answer 1

HELLO DEAR,

Lipids are not soluble in acids it is reason of solubility factor.

Therefore lipids are present in acid insoluble fraction.

Lipids are nonpolar, it is not soluble in water.

Lipids are micromolecules.

lipids are soluble in alcohol.

I HOPE IT'S HELP YOU DEAR,

THANKS.

Answer 2

Correct option is (B) Arranged into structures like cell membrane

• Lipids are micromolecular structures that are present in acid insoluble fraction.
• Acid insoluble fraction refers to part of solution which is insoluble in acid.
• Lipids are not soluble in acid due to their bilayer structure or micellar structure in presence of double and single membrane respectively.
• The structure in the form of vesicles, thus formed is insoluble.
