Question

What is Natural Polymer?

Answer 1

Natural polymers are large molecules composed of repeating units that occur naturally in living organisms. They are derived from biological sources such as plants, animals, and microorganisms.
Here are some examples of natural polymers:

1. Proteins: Proteins are large, complex molecules composed of amino acids. They are vital components of cells and perform various functions in biological systems. Examples of proteins include collagen, keratin, and silk.
2. Polysaccharides: Polysaccharides are polymers made up of sugar units. They serve as energy storage molecules and structural components in organisms. Examples of polysaccharides include cellulose, starch, and chitin.
3. Nucleic Acids: Nucleic acids, such as DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are responsible for storing and transmitting genetic information. They consist of long chains of nucleotide units.
4. Natural Rubber: Natural rubber is a polymer made from the monomer isoprene. It is obtained from the latex sap of certain plants, such as the rubber tree (Hevea brasiliensis). Natural rubber exhibits excellent elasticity and is widely used in various applications.
5. Lignin: Lignin is a complex natural polymer that provides structural support in plants. It is a major component of wood and contributes to its strength and rigidity.
6. Silk: Silk is a natural protein-based fiber produced by silkworms and spiders. It is known for its strength, smoothness, and lustrous appearance.
