Explanation:



Natural polymers are the polymers that are found in nature. They are also known as biopolymers. These are macromolecules that are formed by the combination of same or different monomers. Natural polymers are widely found in living organisms and are responsible for various biological processes. Some examples of natural polymers are proteins, nucleic acids, cellulose, chitin, and natural rubber. Here are some characteristics of natural polymers:

- Natural polymers are biodegradable and environment-friendly.
- They have a complex structure and are often used for specific functions.
- Natural polymers have a wide range of properties, such as strength, elasticity, and flexibility.
- They are often used in medical applications.

Examples of Natural Polymers:

- Proteins: Proteins are long chains of amino acids that are found in living organisms. They are responsible for various biological processes such as the formation of enzymes, hormones, and antibodies.
- Nucleic Acids: Nucleic acids are the building blocks of DNA and RNA. They are responsible for the storage and transmission of genetic information.
- Cellulose: Cellulose is a polymer that is found in the cell walls of plants. It provides structural support to the plant cell.
- Chitin: Chitin is a polymer that is found in the exoskeletons of insects and crustaceans. It provides structural support and protection to these organisms.
- Natural Rubber: Natural rubber is a polymer that is obtained from the sap of the rubber tree. It is used in the production of various rubber products.

Advantages of Natural Polymers:

- Biodegradable and environmentally friendly
- Ability to undergo complex chemical reactions
- Non-toxic and safe for medical applications
- High strength and durability

Disadvantages of Natural Polymers:

- Limited availability and high cost of production
- Variable properties due to natural variability
- Vulnerable to degradation by microorganisms and enzymes
- Limited ability to be modified for specific applications
