Biopolymers are natural polymers produced by living organisms. They are made up of repeating units called monomers, which are linked together to form long chains. Common examples of biopolymers include cellulose, starch, and proteins. These materials play essential roles in biological processes and can be found in various forms, such as plant fibers and animal tissues. Biopolymers are increasingly being studied for their potential applications in sustainable materials and biodegradable products. Unlike synthetic polymers, which can take hundreds of years to decompose, biopolymers can break down more easily in the environment. This makes them a promising alternative for reducing plastic waste and promoting eco-friendly practices.
