Peptides Guide – Comprehensive Information on Peptides, Their Functions ...
Peptides are short chains of amino acids linked by peptide bonds, which are specialized linkages between the nitrogen atom of one amino acid and the carboxyl group of another. Like proteins, peptides belong to a broader category known as polypeptides.
