Amino Acid Azides/Alkynes (14)

Amino acid azides and alkynes are amino acid derivatives bearing azide (-N₃) and alkyne (-C≡C-) groups, respectively. These highly reactive alkyne-azide pairs readily participate in click chemistry reactions—notably copper-catalyzed cycloadditions—to form stable triazole linkages, enabling precise bioconjugation, peptide modification, and drug delivery system construction.
