Any of the various compounds created by cells and living things is referred to as a biomolecule, sometimes known as a biological molecule. Biomolecules come in a wide variety of shapes and sizes and serve a wide range of purposes. Proteins, lipids, nucleic acids, and carbohydrates are the four main categories of biomolecules.

The four main categories of biomolecules are as follows. Lipids, carbohydrates, proteins, and nucleic acids are the names given to them. Proteins are a molecule made up of amino acids and are required for the body to function properly. Lipids are rich in energy and supply energy for all basic functions. Carbohydrates are the body’s main source of energy.

Large molecules called nucleic acids have critical roles in cells, viruses, and—most importantly—in the storage of genetic material. All four molecules are absolutely necessary for life to function as well as for giving the body’s cells the structure and energy they require.
