Biomolecules are organic compounds that are essential for the structure, function, and regulation of living organisms. They serve as the fundamental building blocks of life and play critical roles in various biological processes. There are four main types of biomolecules: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates provide energy and structural support, lipids are involved in energy storage and cell membrane structure, proteins participate in enzymatic reactions and cell signaling, and nucleic acids store and transmit genetic information. These biomolecules interact and collaborate to maintain the integrity and functionality of living organisms, influencing processes such as energy production, molecular transportation, and genetic inheritance. Their proper functioning is essential for the growth, development, and overall survival of living organisms.
