Fmoc-Val-OH, also known as Fmoc-L-Valine, is a high-purity, N-protected amino acid derivative used in Fmoc-based solid-phase peptide synthesis (SPPS). It features an Fmoc-protected α-amino group, allowing selective deprotection and controlled stepwise peptide elongation.
Valine is a branched-chain hydrophobic amino acid that contributes to protein folding, peptide stability, hydrophobic interactions, and secondary structure formation. Fmoc-Val-OH is therefore an important building block for custom peptide synthesis, pharmaceutical research, drug discovery, proteomics, enzyme-substrate studies, protein engineering, and bioconjugation applications.
