Question

Select the correct option:

An unknown liquid collected from a sample of peas, is added to a beaker of water and is vigorously shaken. After few minutes, water and the unknown liquid made two separate layers. To which class of biomolecules, does the unknown liquid most likely belongs?

• A. Polysaccharides
• B. Proteins
• C. Lipids
• D. Enzymes

Answer 1

Answer: (C)

Lipids

The term Lipid was coined by Bloor.

Lipids are the esters of fatty acid and alcohol. These are hydrophobic that is these are insoluble in water but soluble in benzene, ether and chloroform.

As these are insoluble in water when they are added with water they separate to form two layers.

So, the correct option is 'Lipids'
