Question

You have isolated a liquid from a sample of beans. You add the liquid to a beaker of water and shake vigorously. After a few minutes, the water and the other liquid separate into two layers. To which class of biological macromolecules does the unknown liquid most likely belong?

Answer 1

Lipids

Step-by-step explanation:

Lipids:-

Lipids are the bio molecules which are insoluble in aqueous medium and soluble in non polar solvents. They include fatty acids, sterols, fat-soluble vitamins, glycerides, and also phospholipids.

They are hydrophobic bio molecules. Hydrophobic, as the term implies - hydro means water and phobic means fearing.

Thus, the liquid obtained is insoluble in water and thus belongs to lipids.
