The Foundation: Amino Acid N-carboxyanhydrides (NCA)
To appreciate the complexity of these materials, one must understand that amino acid N-carboxyanhydrides (NCA) are a family of heterocyclic organic compounds derived from amino acids. Historically, these were known as Leuchs' anhydrides, and their discovery paved the way for modern macromolecular engineering. These N-carboxyanhydride (NCA) monomers act as the essential building blocks for polypeptides, allowing for a level of control that was previously unattainable in synthetic chemistry.
