Unnatural Amino Acid Derivatives (1059)

Non-natural amino acid derivatives are amino acids that are either absent in nature or occur in extremely limited quantities. Typically produced through artificial synthesis or chemical modification of natural amino acids, these derivatives feature diverse side chain structures and distinct chemical properties. They can be incorporated into engineered proteins using methods such as genetic codon expansion, metabolic labeling, or full and semi-synthesis of proteins. These compounds find extensive applications in fields like biochemistry, drug discovery, materials science, and more.
