<h3>What are biological macromolecules?</h3>
Large, naturally occurring cellular components known as biological macromolecules perform a variety of vital tasks for the development and survival of living things. There are four significant categories of biological macromolecules: lipids, proteins, nucleic acids, and carbohydrates.
Proteins, nucleic acids, and polysaccharides are typical examples of macromolecules.
Macromolecules are enormous molecules that fill a cell and give it vital life-sustaining activities. Macromolecules, for instance, offer structural support, serve as a reservoir for stored energy, have the capacity to store and retrieve genetic information, and can speed up biological operations.
