Hydrogen bonding amides, secondary

Proline is the only amino acid in Table 27.1 that is a secondary amine, and its presence in a peptide chain introduces an amide nitrogen that has no hydrogen available for hydrogen bonding. This disrupts the network of hydrogen bonds and divides the peptide into two separate regions of a helix. The presence of proline is often associated with a bend in the peptide chain. [Pg.1144]

N-hydroxylation is not restricted to primary and secondary amines. For example, nitrogen-based functional groups such as amides, amidino, guanidino, hydrazino, etc. that have at least one nitrogen-hydrogen bond are susceptible to N-hydroxylation. [Pg.98]
