Macromolecules

Macromolecules are large, complex molecules essential for life, composed of smaller units called monomers. The four main types are carbohydrates, which provide energy; proteins, which perform various functions and build structures; lipids, which store energy and make up cell membranes; and nucleic acids, like DNA and RNA, which carry genetic information. These macromolecules are vital for the structure and function of living organisms, supporting processes such as metabolism, growth, and cell communication. Understanding macromolecules helps us grasp how life operates at a molecular level.
