Unnatural Amino Acid Derivatives (1059)

Non-natural amino acid derivatives are amino acids that are either absent in nature or occur only in trace amounts. Typically produced through artificial synthesis or chemical modification of natural amino acids, these derivatives feature diverse side chain groups and distinct chemical properties. They can be incorporated into engineered proteins using methods such as genetic codon expansion, metabolic labeling, or full/semi-synthesis of proteins. Such derivatives find extensive applications in biochemistry, drug discovery, materials science, and other disciplines.
