This results in
the elimination of a water molecule and formation of
a peptide bond –CO–NH– The product of the reaction
is called a dipeptide because it is made up of two
amino acids For example, when carboxyl group of
glycine combines with the amino group of alanine
we get a dipeptide, glycylalanine If a third amino acid combines to a dipeptide, the product is called a
tripeptide
