Linaclotide is a 14-amino acid peptide with the following chemical name: L-cysteinyl-L-cysteinyl-L-glutamyl-L-tyrosyl-L-cysteinyl-L-cysteinyl-Lasparaginyl- L-prolyl-L-alanyl-L-cysteinyl-L-threonyl-glycyl-L-cysteinyl-L-tyrosine, cyclic (1-6), (2-10), (5- 13)-tris (disulfide).
The molecular formula of linaclotide is C59H79N15O21S6 and its molecular weight is 1526.8. The amino acid sequence for linaclotide is shown below:
