"Peptide linkage" is synonymous with "peptide bond." It refers to the covalent bond formed between two amino acids. Consider it the connection points in a string of beads.📿 This linkage joins the carboxyl group of one amino acid to the amino group of another, with the release of water. "Peptide linkage" emphasizes the connection or link created between the amino acids. Like a train connection that links one city to another, these connections link amino acids into the proteins that drive all life. The term underscores its role in creating the long chain of amino acids that form proteins.
