Peptide Bond formation
between successive amino acids
Note that the amino end on the second (R2) amino
acid is added to the carboxyl
end of the
first (R1) amino
acid. The amino
terminus of the R1 amino
acid remains
unchanged, and polypeptide grows in the NC direction.
The repeating N - C(R) - C subunit
remaining after
the dehydration reaction is an amino
acid residue.
