H-Lys(Boc)-OH(cas: 2418-95-3) belongs to amino acids. These amino acids may be present in low concentrations and play a vital part as an intermediate in a biosynthetic pathway, e.g., ornithine, homoserine, or cystathionine. In contrast they may act as a major storage form of nitrogen, e.g., canavanine in the seed of Canavalia ensiformis, or may be formed in high amounts in response to an external stress, e.g., γ-aminobutyrate.Quality Control of H-Lys(Boc)-OH It is possible that some of these nonprotein amino acids may serve as insecticidal or fungicidal agents.

The fascinating functions of proteins and peptides in biol. systems have attracted intense interest to explore their mimics using polymers, including polypeptides synthesized from polymerization The folding, structures and functions of proteins and polypeptides are largely dependent on their sequence. However, sequence-tunable polymerization for polypeptide synthesis is a long-lasting challenge. The application of polypeptides is also greatly hindered by their susceptibility to enzymic degradation Although poly-α/β-peptide has proven to be an effective strategy to address the stability issue, the synthesis of poly-α/β-peptide from polymerization is not available yet. Hereby, we demonstrate a living and controlled copolymerization on α-NCA and β-NTA to prepare sequence-tunable poly-α/β-peptides. This polymerization strategy shows a prominent solvent-driven characteristic, providing random-like copolymers of poly-α/β-peptides in THF and block-like copolymers of poly-α/β-peptides in a mixed solvent of CHCl3/H2O (95/5, volume/volume), and opens new avenues for sequence-tunable polymerization and enables facile synthesis of proteolysis tunable poly-α/β-peptides for diverse applications.
