There are four main types of biomolecules. They are known as lipids, carbohydrates, proteins, and nucleic acids. Lipids are rich in energy; they provide energy for all basic functions, carbohydrates are the body’s most important source of energy, proteins are a molecule made up of amino acids and are needed for the body to function properly.
Nucleic acids are large molecule that plays very important roles in cells, viruses and most importantly it is where the genetic information is stored. All four molecules are extremely vital for the functioning of life and are much needed for providing structure and energy to the cells in the body.
