Polypeptide

Polypeptide

Polypeptides include synthetic peptides, bioactive peptide fragments, peptide hormones, and therapeutic peptide candidates used in biochemical research, structural biology, and drug development. These molecules mimic natural protein segments and participate in signaling pathways, receptor interactions, and enzymatic regulation. Peptide synthesis technologies-including solid-phase synthesis and native chemical ligation-enable precise sequence control and incorporation of modifications such as phosphorylation, methylation, or non-natural amino acids. Polypeptides serve as research tools, vaccine components, diagnostic reagents, and lead compounds for therapeutic development. Their high specificity, low toxicity, and tunability make them increasingly important in modern biomedicine.
