Biomolecules can be classified as lipids on the basis of

The question is incomplete as it does not have the options which are:

A) the presence of many hydroxyl groups and at least one carbonyl group.

B) the presence of at least one amine group and one carboxylic acid group on each molecule.

C) the physical properties of odor, color, and melting point within certain guidelines.

D) a common structure consisting of long hydrocarbon chains.

E) the physical property of solubility in nonpolar organic solvents.

E) the physical property of solubility in nonpolar organic solvents.

Explanation:

Lipids are one of the biomolecules which are involved in the formation of various other complex molecules in the body. The structure of lipids contains a very long hydrocarbon chain which provides hydrophobic to the compound.

Since they are hydrophobic therefore cannot form bonds with the water and thus repel water. This molecule is therefore considered a non-polar molecule. These non-polar molecules are soluble in the non-polar organic solvents only.

Thus, Option-E is the correct answer.
