Boc-Amino Acids for Peptide Synthesis: Focus on Boc-Lys-OH
Peptide synthesis remains a critical technique in modern biological and chemical research, enabling the creation of peptides with specific sequences and functions. These peptides are vital for understanding biological processes, developing new diagnostics, and creating novel therapeutics. A key element in successful peptide synthesis is the use of protected amino acids, and among these, Boc-amino acids, particularly N-alpha-(tert-Butoxycarbonyl)-L-lysine (Boc-Lys-OH, CAS 13734-28-6), are widely favored.
Boc-Lys-OH is a derivative of the amino acid lysine, modified with a tert-butoxycarbonyl (Boc) group on its alpha-amino nitrogen. This Boc group serves as a temporary shield, protecting the highly reactive amino terminus from unwanted reactions during the iterative process of peptide bond formation. The choice of a Boc protecting group is often favored due to its stability under alkaline conditions and its facile removal under mild acidic conditions (typically using trifluoroacetic acid or HCl in organic solvents). This orthogonality is crucial for selective deprotection and coupling steps in peptide synthesis.
Lysine, being a basic amino acid, also possesses a primary amino group on its side chain (epsilon-amino group). Depending on the desired peptide structure and the overall synthetic strategy, this side-chain amino group can be further protected with a suitable orthogonal protecting group, such as Fmoc, Mtt, or Mtr, to prevent interference during peptide chain elongation. The availability of Boc-Lys-OH with various side-chain protections or as the free form makes it a versatile tool for researchers.
When researchers buy Boc-L-lysine, they are typically looking for material with high purity (often stated as ≥95%) and consistent chemical and physical properties. The appearance is usually a white to off-white powder. The molecular formula (C11H22N2O4) and molecular weight (246.30 g/mol) are standard specifications provided by manufacturers. The quality of Boc-Lys-OH directly impacts the yield and purity of the synthesized peptide, making the choice of supplier critical.
The advantage of using Boc-amino acids like Boc-Lys-OH in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS), lies in the robustness of the Boc protection strategy and the ease of its removal. This method has been foundational in developing automated peptide synthesizers and producing a vast array of biologically active peptides.
As a favored Boc-amino acid, Boc-Lys-OH is a staple in the inventory of laboratories focused on peptide chemistry. Sourcing it from reliable manufacturers ensures that researchers have access to a high-quality, well-characterized reagent essential for the efficient and successful construction of peptides, contributing to advancements in drug discovery, chemical biology, and materials science.
