Biomolecules are large molecules essential for life and are mainly composed of carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. The four major types of biomolecules are carbohydrates, lipids, proteins, and nucleic acids. Each plays a crucial role in the structure and function of living organisms. Understanding these molecules is fundamental to understanding how cells work, how we get energy, and how our bodies build and repair tissues.
