Synthetic peptides are typically assembled from the C-terminus to the N-terminus using solid-phase methods. At LifeTein, peptide synthesis is performed using peptide synthesis technology based on Fmoc or t-Boc chemistry to protect the alpha-amino group during stepwise chain assembly.
Unlike natural ribosomal protein synthesis, chemical peptide synthesis is generally carried out from the C-terminus toward the N-terminus.
Fmoc or t-Boc strategies are used to protect the alpha-amino group and control stepwise chain growth.
Each cycle includes deprotection to free the growing amino terminus and coupling of the next amino acid.
After synthesis, the peptide is cleaved from the resin, deprotected, precipitated, washed, and lyophilized.
Sequence length, hydrophobicity, repetitive motifs, and chemical modifications can all affect coupling efficiency, impurity formation, purification difficulty, and final yield. That is why practical synthesis planning depends on more than just the sequence alone.
The behavior of a peptide is strongly influenced by sequence composition, charge, and hydrophobicity. If your peptide is long, hydrophobic, or heavily modified, synthesis and purification may require more careful planning.
