Biologically-modified Amino Acids — a collection of amino acids that have undergone chemical modifications such as acetylation, iodination, or esterification of their carboxyl groups, so that their structures resemble natural metabolites or hormones in the body. These modifications change the functional groups characteristic of standard amino acids into forms that more closely resemble specific bioactive molecules such as thyroid hormones.
Biologically-modified Amino Acids are used by endocrinology and biochemistry researchers to study the synthesis and metabolic pathways of thyroid hormones, including the roles of triiodothyronine and thyroxine in regulating cellular metabolism. Compounds such as Nepsilon-acetyl-lysine are also used as analytical standards for detecting post-translational modifications of proteins, while modified amino acid esters are useful as building blocks in peptide synthesis in organic chemistry laboratories.
Example products in this collection: TCI A2652 692-04-6 Nepsilon-Acetyl-L-lysine, TCI C0396 6020-87-7 Creatine Hydrate, TCI T0453 6893-02-3 3,3',5-Triiodo-L-thyronine, TCI C3610 57-00-1 Creatine, TCI T0245 6106-07-6 L-Thyroxine Sodium Salt Pentahydrate, TCI D0599 63-84-3 3-(3,4-Dihydroxyphenyl)-DL-alanine, TCI T0241 1034-10-2 DL-Thyronine, TCI D0600 59-92-7 3-(3,4-Dihydroxyphenyl)-L-alanine.
Pay attention to the stereochemical configuration (D or L), salt or ester form, and degree of crystal hydration of the compounds, as these factors affect solubility and suitability for the analytical or synthetic methods used. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
