A peptoid is a type of synthetic polymer that resembles a peptide but has a different structure. Unlike peptides, which are made of amino acids linked by peptide bonds, peptoids are composed of N-substituted glycine units. This unique arrangement allows peptoids to exhibit diverse properties and functionalities, making them useful in various applications. Peptoids are studied for their potential in drug development, materials science, and nanotechnology. Their stability and resistance to enzymatic degradation make them promising candidates for creating new therapeutics and biomaterials. Researchers are exploring their use in drug delivery, biomaterials, and nanotechnology applications.
