Peptoids (root from the Greek πεπτός, peptós "digested"; derived from πέσσειν, péssein "to digest" and the Greek-derived suffix -oid meaning "like, like that of, thing like a ______," ), or poly-N-substituted glycines, are a class of biochemicals known as biomimetics that replicate the behavior of biological molecules.^[1] Peptidomimetics are recognizable by side chains that are appended to the nitrogen atom of the peptide backbone, rather than to the α-carbons (as they are in amino acids).
