The Four Macromolecules In Living Organisms

The four macromolecules present in all living organisms are carbohydrates, lipids, proteins, and nuclear acids (Daempfle, 2016). Carbohydrates provide energy. Like carbohydrates, the main function of lipids is to store energy long-term. Proteins are the most common macromolecule in livings systems; they play various roles in our bodies from hair, nails, and skin to having functions in chemical reactions within cells. Nucleic acids play a vital role in the formation of proteins which perform many essential functions for cells.
