Biopolymers are polymers produced by living organisms. They are essential macromolecules found in all living cells and play crucial roles in various biological processes. The most common biopolymers include nucleic acids (DNA and RNA), proteins, and polysaccharides.

Nucleic acids, such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), are responsible for storing and transmitting genetic information. They are composed of repeating nucleotide units. Proteins, built from amino acid monomers, perform a vast array of functions in the body, including catalyzing biochemical reactions (enzymes), providing structural support, and transporting molecules. Polysaccharides, like cellulose and starch, are complex carbohydrates made of monosaccharide units. They serve as energy storage and structural components in plants and animals.

Biopolymers are characterized by their complex structures, often involving intricate folding and assembly, which dictates their specific functions. Their biodegradable nature also makes them attractive for various applications, including sustainable materials, medical devices, and drug delivery systems. The study of biopolymers, known as polymer biology or macromolecular biology, is a vital field for understanding life at the molecular level and for developing new biotechnologies.
