The Struct Linaclotide acetate ural Identity of Linaclotide
Linaclotide is a 14-amino acid synthetic peptide that has garnered attention due to its specific configuration. When reviewing the primary literature, it is consistently identified as a fourteen-membered heterodetic cyclic peptide. This classification is crucial for researchers, as the ring structure is maintained by precise chemical bonding.
The official amino acid sequence is documented as: H–Cys1–Cys2–Glu3–Tyr4–Cys5–Cys6–Asn7–Pro8–Ala9–Cys10–Thr11–Gly12–Cys13–Tyr14.
Linaclotide is a synthetic14-amino acid cyclic peptideand first-in-class guanylate cyclase-C (G-CC) agonist. Linaclotide is structurally related to human Read moreIn the laboratory, observing this 14-amino acid sequence reveals why it is categorized as a 14-amino-acid synthetic cyclic peptide. The stability of the molecule is largely attributed to its three intramolecular disulfide bonds, which connect specific cysteine residues (C1–C6, C2–C10, and C5–C13).

From a technical perspective, the linaclotide sequence contains three inter-cystein Linaclotide - (CAS 851199-59-2) - Peptides e loops, which are integral to its functional geometry. When evaluating high-purity samples, researchers often look for the 14-amino acid residue peptide structure that ensures the molecule remains intact under various conditions.
1. Molecular Formula: C59H79N15O21S6
2. Molecular Weight: Approximately 1,526.8 Da
3. Structural Integrity: The 14 amino acid residues long chain relies on these specific disulfide bridges to maintain its potency and selective interaction with receptors.
During the manufacturing phase, the use of linaclotide linear peptide resin is a standard method for solid-phase synthesis. This process allows for the precise assembly of the 14-amino-acid peptide before the cyclization steps are performed to lock the structure into its final, stable form.
Observations on Peptide Research
In my personal experience, the study of LINACLOTIDE highlights the importanc CN104974229A - Linaclotide solid-phase synthesis method e of regioselective synthesis. Because linaclotide is a synthetic peptide drug, maintaining the correct disulfide bridge placement is non-negotiable. If the bonds are misaligned, the structural properties of the 14-amino acid synthetic peptide sequence change significantly, rendering the molecule ineffective for its intended research applications.
Many researchers who work with this molecule note that linaclotide is a potent and selective guanylate cyclase C agonist. While it is technically an orally administered peptide drug in specific pharmaceutical contexts, those of us in the private research sector focus primarily on its 14-residue structure and its behavior in controlled environments.
Summary of Findings
To summarize, for anyone analyzing the linaclotide peptide sequence, it is essential to focus on:
* The precise H–Cys1–Cys2–Glu3–Tyr4 start of the chain.
* The 14-amino-acid synthetic cyclic peptide arrangement.
* The structural requirement for the three disulfide bridges that give linaclotide its distinct shape.
