The synthesis of peptides, whether for fundamental research or therapeutic development, requires precise chemical tools. Among the most critical are Fmoc-protected amino acids, which form the backbone of Solid Phase Peptide Synthesis (SPPS). This article focuses on Fmoc-Lys(Ac)-OH, exploring its chemical significance and how it contributes to enhanced efficiency in peptide synthesis.

Fmoc-Lys(Ac)-OH, or N-alpha-Fmoc-N-epsilon-acetyl-L-lysine, is a derivative of the essential amino acid lysine. The Fmoc (9-fluorenylmethoxycarbonyl) group serves as a temporary protecting group for the alpha-amino terminus, crucial for the stepwise addition of amino acids during SPPS. The epsilon-amino group of lysine, however, is acetylated in this specific derivative. This acetylation provides unique characteristics to the lysine side chain, influencing the properties of the resulting peptide. Understanding the role of N-alpha-Fmoc-N-epsilon-acetyl-L-lysine purity is paramount, as even minor impurities can lead to complex purification challenges and affect the overall yield and quality of the synthesized peptide.

Researchers often seek to buy Fmoc-Lys(Ac)-OH online for its utility in creating peptides with specific post-translational modifications or for studying the effects of lysine acetylation. The successful integration of acetylated lysine in SPPS allows for the creation of peptide analogs that can mimic natural biological processes or exhibit enhanced stability against enzymatic degradation. This makes Fmoc-Lys(Ac)-OH for peptide synthesis a highly valuable reagent for life science research and pharmaceutical development. The CAS number 159766-56-0 serves as a unique identifier for this specific chemical compound.
