Collection: Unnatural Amino Acid Derivatives

Unnatural Amino Acid Derivatives — gathers non-proteinogenic amino acids and their derivatives whose structures deviate from the twenty standard amino acids, for example through the addition of uncommon side chains, cyclic rings, or additional functional groups on the amino acid backbone.

These Unnatural Amino Acid Derivatives are used by protein chemistry researchers to design peptides and proteins with new properties, for example resistance to degrading enzymes, controlled conformation, or reactive groups for bioorthogonal conjugation. This group is also an important raw material in peptidomimetic engineering, expanded genetic code incorporation, and structure-activity relationship studies for developing model molecules in the laboratory.

Example products in this collection: TCI A0282 56-12-2 4-Aminobutyric Acid, TCI B5684 51513-80-5 6-[(tert-Butoxycarbonyl)amino]hexanoic Acid N-Succinimidyl Ester, TCI A0268 99-05-8 3-Aminobenzoic Acid, TCI B5857 114676-69-6 N-(tert-Butoxycarbonyl)-cis-4-hydroxy-D-proline Methyl Ester, TCI A0269 150-13-0 4-Aminobenzoic Acid, TCI B5867 610791-05-4 1-tert-Butyl 3-Methyl Azetidine-1,3-dicarboxylate, TCI A0276 555-06-6 Sodium 4-Aminobenzoate, TCI B5886 135042-12-5 cis-N-(tert-Butoxycarbonyl)-4-hydroxy-D-proline.

Pay attention to stereochemical configuration, enantiomeric purity, the type of protecting group attached to the amine or side chain, and the solubility of the compound when selecting non-proteinogenic amino acids for a peptide design. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.
