Description

Poly-D-Tyrosine is the D-enantiomer of the amino acid tyrosine, a non-natural isomer used extensively in biochemical and pharmaceutical research. This compound is critical for studying chiral recognition, enzyme specificity, and for the development of novel peptide-based therapeutics and diagnostic agents. It serves as a fundamental building block for researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors who require high-purity, enantiomerically defined amino acids.

Application

• Pharmaceutical Research & Development: As a key chiral precursor in the synthesis of novel peptide drugs and enzyme inhibitors.
• Biochemical Studies: Used to investigate enzyme mechanisms, receptor-ligand interactions, and chiral separation processes.
• Biomaterial Fabrication: Incorporated into synthetic polymers and hydrogels to create bioactive surfaces for cell culture and tissue engineering.
• Diagnostic Reagent Synthesis: Serves as a component in the production of labeled compounds and assay standards.
• Neuroscience Research: Utilized in studies related to tyrosine metabolism and its role in neurotransmitter synthesis.
• Reference Standard: Acts as a high-purity standard for analytical methods like HPLC and mass spectrometry.
