While the concept of molecular weight might seem as simple as summing the atomic masses of all atoms in a molecule, peptide synthesis introduces a crucial element: dehydration. When two amino acids join to form a peptide bond, a molecule of water (H₂O) is eliminated. Therefore, the molecular weight of a peptide is not merely the sum of the molecular weights of its constituent amino acids. Instead, it is the sum of the average molecular weights of the amino acids minus the molecular weight of water for each peptide bond formedThe Peptide calculatorcan calculate the average or monoisotopic molecular weights of standard peptides.
