H-Cys-Ser-Asn-Leu-Ser-Thr-Cys-Val-Leu-Ser-Ala-Tyr-Trp-Arg-Asn-Leu-Asn-Asn-Phe-His-Arg-Phe-Ser-Gly-Met-Gly-Phe-Gly-Pro-Glu-Thr-Pro-NH2 forms a long peptide with two cysteines that support disulfide-mediated conformational stability. Aromatic, polar, and basic residues create a diverse environment for structural exploration. Researchers use it to model folding behavior, binding equilibria, and multivalent interactions. Applications span structural biology, peptide engineering, and motif-function analysis.
