Why? Biological Molecules What are the building blacks of life? From the smallest single-celled organism to the tallest tree, all life depends on the properties and reactions of four classes of organic (carbon-based) compounds carbohydrates, lipids, proteins, and nucleic acids. These organic molecules are the building blocks of all living things, and are responsible for most of the structure and functions of the body, including energy tomge, insulation, growth, repair, communica tion, and transfer of hereditary information. Simple organic molecules can be joined together to form all the essential biological molecules needed for life.
