Peptoid structures are synthetic polymers that resemble proteins but differ in their building blocks. While proteins are made of amino acids, peptoids are composed of N-substituted glycine units. This unique structure allows peptoids to adopt diverse shapes and functions, making them useful in various applications, including drug delivery and materials science. One of the key advantages of peptoids is their stability against enzymatic degradation, which enhances their potential for therapeutic use. Researchers are exploring their ability to mimic natural proteins, leading to innovations in fields such as biotechnology and nanotechnology.
