Why is it important to learn about biomolecules

The explanation is given in the explanation section.

Explanation:

Living organisms make biomolecules, and they are made because of their functional characteristics. Most of the biomolecules do not exist outside of living organisms because they are too complex to be created by chance chemical collisions. 

The four primary purposes of biomolecules are:

- Structure (some proteins)

- Energy storage and release (carbohydrates)

- Protective layers (lipids)

- Information storage and communication (DNA, RNA, endocrines of numerous various types and manipulated molecules, such as fatty acids)
