WebJul 20, 2024 · Peptide (amide) bonds in proteins and polypeptides are subject to spontaneous (nonenzymatic) hydrolysis in water. Although this amide to carboxylate conversion is thermodynamically a downhill reaction, peptide bonds are kinetically very stable (they react slowly) at neutral pH. WebWhen both the carboxylic acid and the amine are in the same molecule, amide formation produces lactams. A lactam is a cyclic amide, where the amide group is part of the ring. Draw the structure of the product (s) obtained from acid hydrolysis of the following lactams. This problem has been solved! WebThe hydrolysis of amides in base is analogous to the saponiﬁcation of esters. In base, the reaction is driven to completion by formation of the carboxylic acid salt. The conditions for both acid- and base-promoted amide hydrolysis are considerably more severe than the corresponding reactions of esters. That is, amides are considerably less reac- outback fishing
