PRIMARY STRUCTURE REFERENCE
See the sequence behind the compound
A peptide is its sequence — the ordered chain of amino acids that defines its identity and the exact mass a lab confirms on the certificate. Pick a compound to view its primary structure, molecular formula and residue chemistry.
Canonical reference sequences and published constants, shown for research context. Molecular formula and average mass are nominal values for the parent peptide; exact identity for a given batch is confirmed by LC–MS on its Certificate of Analysis.
