non-Proteinogenic Amino Acids — covers amino acids not included among the 20 standard amino acids that make up proteins, including modified side-chain analogs, homologs, as well as salt forms and cyclic or non-alpha derivatives. This group serves as building material for specialized peptide synthesis and for studies of protein structure-function beyond the standard genetic code.
non-Proteinogenic Amino Acids are widely used in peptide chemistry, biochemistry, and molecular pharmacology research as building units for modified peptides, reference compounds for receptor and enzyme research, or precursors for asymmetric synthesis. Derivatives such as esters, sulfate salts, and long-chain analogs are used to study enzyme selectivity, amino acid transport, and the design of structural analogs in biochemistry and biotechnology research.
Example products in this collection: TCI A0282 56-12-2 4-Aminobutyric Acid, TCI B6405 76410-58-7 4-Borono-L-phenylalanine (contains varying amounts of Anhydride), TCI A0319 1927-25-9 DL-Homoserine, TCI C0018 2219-31-0 L-Canavanine Sulfate, TCI A0323 62-57-7 2-Aminoisobutyric Acid, TCI C0049 541-15-1 L-Carnitine, TCI A0382 644-90-6 DL-2-Amino-n-octanoic Acid, TCI C0050 461-05-2 DL-Carnitine Hydrochloride.
Pay attention to the chemical form (free acid, salt, or ester), stereochemical configuration (D, L, or DL), and the purity level suitable for peptide synthesis applications and biochemical studies. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
