Peptoids are synthetic polymers that resemble proteins but have a different structure. They are made up of a chain of amino acids where the side chains are attached to the nitrogen atom instead of the carbon atom. This unique arrangement gives peptoids enhanced stability and resistance to degradation, making them useful in various applications. Due to their customizable nature, peptoids can be designed to interact with specific biological targets, such as proteins or DNA. This property makes them valuable in fields like drug development, biotechnology, and materials science, where they can be used for creating new therapeutics or advanced materials.
