Peptide Sequencing

Meaning

Peptide Sequencing is the analytical laboratory technique used to determine the exact order of amino acid residues in a peptide or protein. This process is foundational in molecular science and clinical endocrinology, as the specific sequence dictates the molecule’s three-dimensional structure, function, and receptor binding affinity. Accurate sequencing is essential for the quality control and development of bio-identical peptides and for identifying novel therapeutic targets within the body’s complex signaling network. It is the definitive method for molecular identification.
