Synthetic amino acid analogs

Definition

Synthetic amino acid analogs are artificially created compounds that resemble natural amino acids in structure and function but have slight modifications in their chemical composition. These analogs are often used to study protein function, enzyme activity, and to develop new therapeutics, as their altered properties can provide insights into the role of specific amino acids within proteins.
