Biological molecules are also known as biomolecules are what we eat. They are what all living things needed to survive. They come in form of carbohydrates,  proteins, lipids, and nucleic acids.  

Food gives the body the nourishment it requires to survive. Many of these essential nutrients are biological macromolecules or big molecules that are required for life. These macromolecules called polymers are composed of various arrangements of smaller organic molecules called monomers.

Carbohydrates, lipids, proteins, and nucleic acids are the four primary groups of biological macromolecules; each one is a significant cell constituent and serves a variety of activities. 

Carbohydrates are a necessary component in our diet;

  • cereals,
  • fruits, and;
  • vegetables

are all organic sources of carbohydrates.

Carbohydrates supply energy to the body, notably glucose. It is a simple sugar found in starch and found in many basic meals.

Proteins are the most common organic molecules in biological systems and it is the most universal range of activities of any macromolecule. A biological system's cells may contain protein complexes, each with a distinct purpose.

Lipids are a broad category of molecules that are predominantly nonpolar in nature. In a cell, lipids play a variety of functions. Cells reserve energy in the form of lipids for long usage. 

Nucleic acids are the most crucial macromolecules for the continuation of life. They include the genetic information of a cell as well as information for the cell's functionality.

Therefore, we can conclude that the importance of biological molecules is important in human life.
