What Are the 4 Major Macromolecules and How Are They Made?

Living organisms consist of four major macromolecules: carbohydrates, lipids, proteins, and nucleic acids. These biomolecules are formed from smaller units called monomers. Carbohydrates provide energy, lipids store energy, proteins build tissues, and nucleic acids store genetic information. Each macromolecule has distinct monomers and functions essential for life.
