Unnatural Amino Acid Derivatives (441)

Non-natural amino acid derivatives are amino acids that are either absent in nature or occur in extremely small quantities. 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 techniques such as genetic codon expansion, metabolic labeling, or full/semi-synthesis of proteins. Their applications span across biochemistry, drug development, materials science, and various other fields.
