Amides derived from two or more amino carboxylic acid molecules (the same or different)
by formation of a
covalent bond from the carbonyl carbon of one to the nitrogen atom of another with formal loss
of water. The term is usually applied to structures formed from α-amino acids, but
it includes those derived from any amino carboxylic acid.
(R may be any organyl group, commonly but not necessarily one found in natural amino
acids)
