Chem and Physics section - correct answer What atom is the site of covalent attachment of AMC to the model tetrapeptide used in the studies? - correct answer Because AMC is attached to the peptide on the carboxyl side. This suggests that an amide linkage involving the N atom in AMC is used to covalently attach the fluorophore to the peptide *a peptide bond between amino acids= covalent bond between carboxyl group of 1 amino acid to amino group of other, releasing water What expression give...
